Missed to add:
I had referred to other reference driver's and thought of keeping it.
So I'll drop this patch in V5 as it is not much value addition here.
Sorry for the confusion

[PATCH v4 10/14] dtoc: extend dtoc to use struct driver_info when linking nodes
In the current implementation, when dtoc parses a dtb to generate a struct
platdata it converts the information related to linked nodes as pointers
to struct platdata of destination nodes. By doing this, it makes
difficult to get pointer to udevices created based on these
information.
This patch extends dtoc to use struct driver_info when populating
information about linked nodes, which makes it easier to later get
the devices created. In this context, reimplement functions like
clk_get_by_index_platdata() which made use of the previous approach.

[PATCH v4 12/14] arm: dts: include gpio nodes for card detect
Several MMC drivers use GPIO for card detection with cd-gpios property in
the MMC node pointing to a GPIO node. However, as U-Boot tries to save
space by keeping only required nodes using u-boot* properties, several
devices tree result in having only in the MMC node but not the GPIO node
associated to cd-gpios.
This patch, fixes several ocurrence of this issue.

[PATCH v4 11/14] dm: doc: update of-plat with new phandle support
Update documentation to reflect the new phandle support when OF_PLATDATA
is used. Now phandles are implemented as pointers to U_BOOT_DEVICE,
which makes it possible to get a pointer to the actual device.

[PATCH v4 08/14] core: extend struct driver_info to point to device
Currently when creating an U_BOOT_DEVICE entry a struct driver_info
is declared, which contains the data needed to instantiate the device.
However, the actual device is created at runtime and there is no proper
way to get the device based on its struct driver_info.
This patch extends struct driver_info adding a pointer to udevice which
is populated during the bind process, allowing to generate a set of
functions to get the device based on its struct driver_info.

[PATCH v4 03/14] core: add support for U_BOOT_DRIVER_ALIAS
Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.
To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

a compatible name that matches a driver name generate a working
entry.
In order to improve this behaviour, this patch adds to dtoc the
capability of scan drivers source code to generate a list of valid driver
names and aliases. This allows to generate U_BOOT_DEVICE entries using
valid driver names and rise a warning in the case a name is not valid.

[PATCH v4 05/14] dtoc: add option to disable warnings
As dtoc now performs checks for valid driver names, when running dtoc
tests several warnings arise as these tests don't use valid driver
names.
This patch adds an option to disable those warning, which is only
intended for running tests.

[PATCH v4 01/14] drivers: rename drivers to match compatible string
When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.
In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

[PATCH v3 08/14] core: extend struct driver_info to point to device
Currently when creating an U_BOOT_DEVICE entry a struct driver_info
is declared, which contains the data needed to instantiate the device.
However, the actual device is created at runtime and there is no proper
way to get the device based on its struct driver_info.
This patch extends struct driver_info adding a pointer to udevice which
is populated during the bind process, allowing to generate a set of
functions to get the device based on its struct driver_info.

[PATCH v3 12/14] arm: dts: include gpio nodes for card detect
Several MMC drivers use GPIO for card detection with cd-gpios property in
the MMC node pointing to a GPIO node. However, as U-Boot tries to save
space by keeping only required nodes using u-boot* properties, several
devices tree result in having only in the MMC node but not the GPIO node
associated to cd-gpios.
This patch, fixes several ocurrence of this issue.

[PATCH v3 10/14] dtoc: extend dtoc to use struct driver_info when linking nodes
In the current implementation, when dtoc parses a dtb to generate a struct
platdata it converts the information related to linked nodes as pointers
to struct platdata of destination nodes. By doing this, it makes
difficult to get pointer to udevices created based on these
information.
This patch extends dtoc to use struct driver_info when populating
information about linked nodes, which makes it easier to later get
the devices created. In this context, reimplement functions like
clk_get_by_index_platdata() which made use of the previous approach.

[PATCH v3 04/14] dtoc: add support to scan drivers
Currently dtoc scans dtbs to convert them to struct platdata and
to generate U_BOOT_DEVICE entries. These entries need to be filled
with the driver name, but at this moment the information used is the
compatible name present in the dtb. This causes that only nodes with
a compatible name that matches a driver name generate a working
entry.
In order to improve this behaviour, this patch adds to dtoc the
capability of scan drivers source code to generate a list of valid driver
names and aliases. This allows to generate U_BOOT_DEVICE entries using
valid driver names and rise a warning in the case a name is not valid.

[PATCH v3 05/14] dtoc: add option to disable warnings
As dtoc now performs checks for valid driver names, when running dtoc
tests several warnings arise as these tests don't use valid driver
names.
This patch adds an option to disable those warning, which is only
intended for running tests.

[PATCH v3 01/14] drivers: rename drivers to match compatible string
When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.
In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

[PATCH v3 03/14] core: add support for U_BOOT_DRIVER_ALIAS
Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.
To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

[PATCH 0/2] arm: mvebu: a38x: USB2 serdes changes
While debugging this issue with Marvell I found the change that was made to Marvell's u-boot but doesn't appear to have made it upstream. We're in the process of checking the affect it has on the USB compliance testing we're doing. I have regression tested it against a couple of USB devices (Ethernet and Storage). But it'd be good to get some more coverage against other hardware platforms and USB devices.

[PATCH 2/2] arm: mvebu: a38x: Adjust UTMI PHY parameters
When running USB compliance tests on our Armada-385 hardware platforms
we have seen some eye mask violations. Marvell's internal documentation
says: Based on silicon test results, it is recommended to change the
impedance calibration threshold setting to 0x6 prior to calibration.
Port changes from Marvell's u-boot fork[1] to address this.

OK, but I suspect the parameter check in
sifive_fu540_prci_clk_request() is not necessary too as currently the
codes work well.

We could check if the issue on your board is due to: commit 6333cbb3817ed551cd7d4e92f7359c73ccc567fc Author: Michael Walle Date: Thu May 7 00:11:58 2020 +0200 phy: atheros: ar8035: remove static clock config We can configure the clock output in the device tree. Disable the hardcoded one in here. This is highly board-specific and should have never been enabled in the PHY driver. If bisecting shows that this commit breaks your board it probably depends on the clock output of your Atheros AR8035 PHY. Please have a look at doc/device-tree-bindings/net/phy/atheros.txt. You need to set "clk-out-frequency = <12500>" because that value was the hardcoded value until this commit. Signed-off-by: Michael Walle Acked-by: Joe Hershberger On your board, are you able to measure with a scope the AR8035 CLK_25M pin? Prior to this commit the CLK_25M was hardcoded to output a 125MHz clock. Now that this setting from the ar8035 phy driver is gone we should pass this information in some form: - We tried via devicetree with the "qca,clk-out-frequency" property, but it did not work. This is an area where you could add some debug prints inside drivers/net/phy/atheros.c and see if if qca,clk-out-frequency is being parsed correctly to configure a 125MHz clock output. This is the method I used on mx6cuboxi last week and it works. - Other way to configure the AR803x is via board code. Please try to copy the ar8031_phy_fixup() and board_phy_config() from board/freescale/mx6sabresd/mx6sabresd.c into your board file. (I plan to remove this board PHY code in mx6sabresd after 2020.07 and use "qca,clk-out-frequency" to do the job).

[PATCH v3 0/2] Assorted fixes related to reserved memory
This series has few small assorted fixes related to reserved memory support in RISC-V. The series is rebased on top of the following series http://patchwork.ozlabs.org/project/uboot/patch/1591767391-2669-2-git-send-email-bmeng...@gmail.com/ Changes form v2->v3: 1. Dropped bootefi patch as it is already merged. 2. Fixed minor typos. Changes from v1->v2: 1. Rebased on top of the Bin's series. Dropped the fix generic fdtdec code. 2. Added bootefi fix.

[PATCH v3 2/2] riscv: Use optimized version of fdtdec_get_addr_size_no_parent
fdtdec_get_addr_size_no_parent is not an optimized version if parent
node is already available with the caller.
Use fdtdec_get_addr_size_auto_parent to read the "reg" property

Yes, but I would also have to skip a specific number of lines, e.g.
console_record_reset();
run_command("pinmux", 0);
ut_assert_nextline_contains("");
ut_assert_nextline_contains("");
ut_assert_nextline_contains("Usage:");
console_record_reset();

That's ok, but still fairly brittle in how it tests the output.
Oh well, perhaps I'll add something like that next revision...

I thought these ones were intended to be skipped? I'm perhaps just

That sounds good.
But in general, my point is that we should avoid displaying a message
when things are working as intended, only when some action has to be
taken. When everything is right, there should not be any warnings or
failures IMO.

I just tested mainline U-Boot and Ethernet works fine on a imx6qp sabresd board:

What is the exact failure you see? Is the Ethernet PHY found at the

On tbs2910 does the AR8031 generate a 125MHz clock to the i.MX6Q Ethernet?
If so, does the change below help (I am assuming the PHY is located at
address 1, if not, please adjust the @ and reg accordingly)?

Re: [PATCH U-BOOT v3 00/30] PLEASE TEST fs: btrfs: Re-implement btrfs support using code from btrfs-progs
I shall compile for different platforms with and without these patches to see how much these patches increase the size of the resulting U-Boot binary. Maybe it will show us that it is finally time to look into LTO for U-Boot.
[PATCH U-BOOT v3 28/30] fs: btrfs: Imeplement btrfs_list_subvols() using new infrastructure

[PATCH U-BOOT v3 18/30] fs: btrfs: inode: Allow next_length() to return value > BTRFS_NAME_LEN
From: Qu Wenruo
All existing next_length() caller handles return value > BTRFS_NAME_LEN,
so there is no need to do BTRFS_NAME_LEN check in next_length().
But still, we want to exit early if we're beyond BTRFS_NAME_LEN, so this
patch makes next_length() exit as soon as we're beyond BTRFS_NAME_LEN.

[PATCH U-BOOT v3 15/30] fs: btrfs: Crossport open_ctree_fs_info() from btrfs-progs
From: Qu Wenruo
open_ctree_fs_info() is the main entry point to open btrfs.
This version is a simplfied version of __open_ctree_fd() of btrfs-progs,
the main differences are:
- Parameters on how to specify a block device
Instead of @fd and @path, U-Boot uses blk_desc and disk_partition_t.
- Remove open_ctree flags
There won't be multiple open ctree modes in U-Boot.
Otherwise functions structures are all kept the same.
With open_ctree_fs_info() implemented, also introduce the global
current_fs_info pointer to show the current opened btrfs.

Although in theory we can still support multiple devices, we don't have

Since the old code is using __btrfs_path/__btrfs_root which is different
from the regular extent buffer based one, we add "__" prefix for the old

[PATCH U-BOOT v3 25/30] fs: btrfs: Implement btrfs_file_read()
From: Qu Wenruo
This version of btrfs_file_read() has the following new features:
- Tries all mirrors
- More handling on unaligned size
- Better compressed extent handling
The old implementation doesn't handle compressed extent with offset
properly: we need to read out the whole compressed extent, then
decompress the whole extent, and only then copy the requested part.

[PATCH U-BOOT v3 19/30] fs: btrfs: Implement btrfs_lookup_path()
From: Qu Wenruo
This is the extent buffer based path lookup routine.
To implement this, btrfs_lookup_dir_item() is crossported from
btrfs-progs, and implements btrfs_lookup_path() from scratch.
Unlike the existing __btrfs_lookup_path(), since btrfs_read_fs_root()
will check whether a root is a orphan at read time, there is no need to
check root backref, this makes the code a little easier to read.

[PATCH U-BOOT v3 20/30] fs: btrfs: Use btrfs_iter_dir() to replace btrfs_readdir()
From: Qu Wenruo
Use extent buffer based infrastructure to re-implement btrfs_readdir().
Along this rework, some small corner cases fixed:
- Subvolume tree mtime
Mtime of a subvolume tree is recorded in its root item, since there is
no INODE_ITEM for it.
This needs extra search from tree root.
- Output the unknown type
If the DIR_ITEM is corrupted, at least don't try to access the memory
out of boundary.

[PATCH U-BOOT v3 07/30] fs: btrfs: Crossport structure accessor into ctree.h
From: Qu Wenruo
This brings all structure accessors from btrfs-progs/ctree.h, as in
kernel's ctree.h.
All these accessors handle the endian convert at runtime, and since all
of them are defined as static inline functions, those which aren't used
won't take space in resulting binary.

This patch copies the core function, btrfs_search_slot(), from
btrfs-progs.
This version has the following functionality removed:
- The ability to COW tree block
Related code is commented out, and can be enabled in the future.
- The readahead functionality
This is abused in kernel. Remove it completely.
With the core function in place, btrfs developers should feel at home now.
This also crossports supporting code like btrfs_previous_item() to
ctree.[ch].

[PATCH U-BOOT v3 08/30] fs: btrfs: Crossport volumes.[ch] from btrfs-progs
From: Qu Wenruo
This patch crossports volumes.[ch] from btrfs-progs, including:
- btrfs_map_block()
The core mechanism to map btrfs logical address to physical address.
This version includes multi-device support, along with RAID56 support.
- btrfs_scan_one_device()
This is the function to register one btrfs device to the list.
This is the main part of the multi-device btrfs assembling process.
Although we're not going to support multiple devices until U-Boot
allows us to scan one device without actually opening it.

[PATCH U-BOOT v3 10/30] fs: btrfs: Rename struct btrfs_path to struct __btrfs_path
From: Qu Wenruo
To avoid name conflicting between the extent buffer based btrfs_path
from btrfs-progs, rename struct btrfs_path to struct __btrfs_path.
Also rename btrfs_free_path() to __btrfs_free_path() to avoid conflicts.

From: Qu Wenruo
This version includes all needed on-disk format from kernel.
Only need to modify the include headers for U-Boot, everything else is
untouched.
Also, since U-Boot btrfs is using a different endian convert timing (at
tree block read time), it needs some forced type conversion before
proper crossport.

[PATCH U-BOOT v3 09/30] fs: btrfs: Crossport read_tree_block() from btrfs-progs
From: Qu Wenruo
This is the one of the basic stone function for btrfs, which:
- Resolves the chunk mappings
- Reads data from disk
- Does various sanity check
With read_tree_block(), we can finally crossport needed btrfs btree
operations to U-Boot.

[PATCH U-BOOT v3 02/30] fs: btrfs: Add more checksum algorithms
From: Qu Wenruo
This mostly crossports crypto/hash.[ch] from btrfs-progs.
The differences are:
- No blake2 support
No blake2 related library in U-Boot yet.
- Use uboot xxhash/sha256 directly
No need to implement the code as U-Boot has already provided the
interface.
This adds the support for the following csums:
- SHA256
- XXHASH

[PATCH U-BOOT v3 03/30] fs: btrfs: Crossport btrfs_read_dev_super() from btrfs-progs
From: Qu Wenruo
This patch uses generic code from btrfs-progs to read one super block
from block device.
To support the btrfs-progs coding style, the following is also
crossported:
- BTRFS_SETGET_FUNC for btrfs_super_block
- btrfs_check_super() function
- Move btrfs_read_superblock() to disk-io.[ch]
Since super.c only contains pretty small amount of code, and
the extra check will be covered in later root read patches.
Differences between this implementation and btrfs-progs:
- No sbflags/sb_bytenr support
Since we only need to read the primary super block (like kernel),
sbflags/sb_bytenr used by super block recovery is not needed.
This also changes the following behavior of U-Boot btrfs:
- Only reads the primary super block
The old implementation reads all 3 super blocks, and also one
non-existing backup.
This is not correct, especially if there is another filesystem created
on the device but old superblocks are not rewritten.
Just like kernel, we only check the primary super block.

[PATCH U-BOOT v3 05/30] fs: btrfs: Crossport extent-cache.[ch] from btrfs-progs
From: Qu Wenruo
This patch implements an infrastructure to insert/search/merge an extent
range (with variable length).
This provides the basis for later extent buffer cache used in btrfs.

[PATCH U-BOOT v3 00/30] PLEASE TEST fs: btrfs: Re-implement btrfs support using code from btrfs-progs
Hello, this is a cleaned up version of Qu's patches that reimplements U-Boot's btrfs driver with code from btrfs-progs. I have tested this series, found and corrected one bug (failure when accesing files via symlinks), and it looks it is working now, but I would like more people to do some testing. There are a lot of checkpatch warnings and errors left, I shall fix this in the future. Marek Changes since v2: - fixed btrfs_lookup_path() in patch 19 to correctly handle symlinks - commit messages were updated some - for example they used the word "crossport" in 3 formats: "crossport", "cross-port" and "cross port", this was changed to "crossport" - corrected some typos - some English sentences were a bit weirdly written - fixed 2 compiler warnings (one use of maybe uninitialized variable and one printf specifier warning) - indentation in some places was wrong (usage of 8 spaces instead of a tab, for example) - added my Reviewed-by - the last patch, adding btrfs mailing list to MAINTAINRES, also adds Qu as designated reviewer, so that people add him to Cc when they send patches Changes since v1: - Implement btrfs_list_subvols() In v1 it's completely removed thus would cause problem if btrfsolume command is compiled in. - Rebased to latest master Only minor conflicts due to header changes. - Allow next_legnth() to return value > BTRFS_NAME_LEN Below is Qu's explanation, from cover letter of v2: The current btrfs code in U-boot is using a creative way to read on-disk data. It's pretty simple, involving the least amount of code, but pretty different from btrfs-progs nor kernel, making it pretty hard to sync code between different projects. This big patchset will rework the btrfs support, to use code mostly from btrfs-progs, thus all existing btrfs developers will feel at home. During the rework, the following new features are added: - More hash algorithm support SHA256 and XXHASH support are added. BLAKE2 needs more backport, will happen in a separate patchset. - The ability to read degraded RAID1 Although we still only support one device btrfs, the new code base can choose from different copies already. As long as new device scan interface is provided, multi-device support is pretty simple. - More correct handling of compressed extents with offset For compressed extent with offset, we should read the whole compressed extent, decompress them, then copy the referred part. There are some more features incoming, with the new code base it would be much easier to implement: - Data checksum support The check would happen in read_extent_data(), btrfs-progs has the needed facility to locate data csum. - BLAKE2 support Need BLAKE2 library cross ported. For btrfs it's just several lines of modification. - Multi-device support along wit degraded RAID support We only need an interface to scan one device without opening it. The infrastructure is already provided in this patchset. These new features would be submitted after the patchset get merged, since the patchset is already large, I don't want to make it more scary. Although this patchset look horribly large, most of them are code copy from btrfs-progs. E.g extent-cache.[ch], rbtree-utils.[ch], btrfs_btree.h. And ctree.h has over 1000 lines copied just for various accessors. While for disk-io.[ch] and volumes-io.[ch], they have some small modifications to adapt the interface of U-boot. E.g. btrfs_device::fd is replace with blkdev_desc and disk_partition_t. The new code for U-boot are related to the following functions: - btrfs_readlink() - btrfs_lookup_path() - btrfs_read_extent_inline() - btrfs_read_extent_reg() - lookup_data_extent() - btrfs_file_read() - btrfs_list_subvols() Qu Wenruo (30): fs: btrfs: Sync btrfs_btree.h from kernel fs: btrfs: Add more checksum algorithms fs: btrfs: Crossport btrfs_read_dev_super() from btrfs-progs fs: btrfs: Crossport rbtree-utils from btrfs-progs fs: btrfs: Crossport extent-cache.[ch] from btrfs-progs fs: btrfs: Crossport extent-io.[ch] from btrfs-progs fs: btrfs: Crossport structure accessor into ctree.h fs: btrfs: Crossport volumes.[ch] from btrfs-progs fs: btrfs: Crossport read_tree_block() from btrfs-progs fs: btrfs: Rename struct btrfs_path to struct __btrfs_path fs: btrfs: Rename btrfs_root to __btrfs_root fs: btrfs: Crossport struct btrfs_root to ctree.h fs: btrfs: Crossport btrfs_search_slot() from btrfs-progs fs: btrfs: Crossport btrfs_read_sys_array() and btrfs_read_chunk_tree() fs: btrfs: Crossport open_ctree_fs_info() from btrfs-progs fs: btrfs: Rename path resolve related functions to avoid name conflicts fs: btrfs: Use btrfs_readlink() to implement __btrfs_readlink() fs: btrfs: inode: Allow next_length() to return value > BTRFS_NAME_LEN fs: btrfs: Implement btrfs_lookup_path() fs: btrfs: Use btrfs_iter_dir() to replace btrfs_readdir() fs: btrfs: Use btrfs_lookup_path() to implement btrfs_exists() a

It's not useless information. It's what I pointed to in another part of
the thread as to why we're skipping tests we didn't expect to skip.

This one is actually one I dug in to a bit, and I don't like how pytest
handles. You can't add a custom parameter checker, AFAICT, you can only
have empty params be skip or xfail.
I think we could condense the output a little bit as @pytest.mark things
get condensed, but pytest.skip in a test do not (as it counts line
number). That's what got me looking for a way to mark that a config
needs to exist, but that isn't supported. But we could condense some of
the network related stuff by having a single test / helper for network
configuration rather than duplicating it, and then mark network tests as
depending on it.

But still getting the same error code (-2). On board is the GD25Q127C from Gigadevice. The device ID for the operation code 0x9F according to the datasheet should be 0xC84018. I also found this device ID in the SPI-NOR IDS file.

On a different note, I think we should look at:
https://gitlab.denx.de/u-boot/custodians/u-boot-efi/-/jobs/112376
and:
https://gitlab.denx.de/u-boot/custodians/u-boot-efi/-/jobs/112380
as it shows that the reason we probably skip the test_fs/test_mkdir.py
tests is that since board is literal, we don't match sandbox on
sandbox_flattree. That answers one outstanding question about why we
skip some tests and not others at least.

There is no switch in pytest to display this selectively.

[PATCH 2/2] efi_loader: size of secure boot variables
The variables SetupMode, AuditMode, DeployedMode are explicitly defined as
UINT8 in the UEFI specification. The type of SecureBoot is UINT8 in EDK2.
Use variable name secure_boot instead of sec_boot for the value of the
UEFI variable SecureBoot.
Avoid abbreviations in function descriptions.

[PATCH 1/2] efi_loader: type of efi_secure_mode
Variable efi_secure_mode is meant to hold a value of enum efi_secure_mode.
So it should not be defined as int but as enum efi_secure_mode.
