I don't remember well, but I have expected that even a whole disk be
represented as a partition (0).

[PATCH 7/7] reset: sunxi: Reuse the platform data from the clock driver
The clock and reset drivers use the exact same platform data. Simplify
them by sharing the object. This is safe because the parent device
(the clock device) always gets its driver model callbacks run first.

[PATCH 4/7] clk: sunxi: Use a single driver for all variants
Now that all of the variants use the same bind/probe functions and ops,
there is no need to have a separate driver for each variant. Since most
SoCs contain two variants (the main CCU and PRCM CCU), this saves a bit
of firmware size and RAM.

[PATCH 5/7] clk: sunxi: Convert driver private data to platform data
All of the driver private data should really be platform data since it
is determined statically (selected by the compatible string or extracted
from the devicetree). Move everything to platform data, so it can be
provided when binding the driver. This is useful for SPL, or for
instantiating the driver as part of an MFD.

[PATCH 1/7] clk: sunxi: Store the array sizes in the CCU descriptor
The reset array size is currently used for bounds checking in the reset
driver. The same bounds check should really be done in the clock driver.
Currently, the array size is provided to the reset driver separately
from the CCU descriptor, which is a bit strange. Let's do this the usual
way, with the array sizes next to the arrays themselves.

[PATCH 2/7] clk: sunxi: Prevent out-of-bounds gate array access
Because the gate arrays are not given explicit sizes, the arrays are
only as large as the highest-numbered gate described in the driver.
However, only a subset of the CCU clocks are needed by U-Boot. So there
are valid clock specifiers with indexes greater than the size of the
arrays. Referencing any of these clocks causes out-of-bounds access.
Fix this by checking the identifier against the size of the array.

[PATCH 0/7] clk: sunxi: Out-of-bounds access fix and driver cleanup
This series fixes an issue with out-of-bounds access to the gate array (patches 1-2), uses the rearranged array size information to remove a bunch of duplicate code (patches 3-4), and then simplifies how the reset driver is bound (patches 5-7). The original motivation for these changes was adding a driver for the legacy A31/A23/A33 PRCM binding (which I will send separately), and trying to use OF_PLATDATA in SPL (which did not work out). But I think at least some of the cleanup is worth applying on its own. Patch 4 is generally the same change I made between v1 and v2 of the pinctrl series, using some #ifdefs to share a U_BOOT_DRIVER. It's not quite as clean as the pinctrl case, because here the SoC-specific parts are in different files, so all of the CCU descriptors have to be global.

Why not (enhance and) re-use dev_tag_get_ptr()?
Both functions, at least, share the syntax and even the semantics
from user's viewpoint.

This counter allow to remove the function stm32_usbphyc_is_init
and it is a preliminary step for ck_usbo_48m introduction.
Is it necessary to disable this clock before booting to Linux? If it isn't,
then perhaps it is simpler to just not disable the clock.

Or you do have some more information? Hello! I looked at it again and it is more complicated as I initially thought. There are two options how L2 cache on P2020 may be used as SRAM. First option is the classic way with locking lines, like it is done on other architectures. Second option seems to be P1/P2 specific as it is *not* documented in e500 core reference manual, but in P2020 SoC reference manual, and this option changes L2 operation from Cache to Memory-Mapped SRAM mode. Downloading P2020 reference manual (rev2) requires NXP account: https://www.nxp.com/webapp/Download?colCode=P2020RM But some older version (rev0) can be found on internet, e.g.: http://m4udit.dinauz.org/P2020RM_rev0.pdf I checked U-Boot code and it is for L2 SRAM configuration uses second option, therefore not via L2 locked lines, but as L2 memory-mapping. P2020 reference manual in section "Memory-Mapped SRAM Coherency Rules" contains: Accesses to memory-mapped SRAM are cacheable only in the corresponding e500 L1 caches. External accesses must be marked cache-inhibited or be performed with non-caching transactions. So based on the fact that L2 is in U-Boot in memory-mapped SRAM mode, not in cache mode with locked lines and that P2020 RM explicitly says that memory-mapped SRAM can be cacheable in L1, my understanding is that TLB mapping for L2 SRAM should work with Caching-inhibited bit set and also with unset (when unset then caching is disabled at L1 level). Is my deduction correct? Priyanka, Sinan, any idea?

[PATCH v1 15/17] rockchip: rk3066: config nand data pins in spl
From: Paweł Jarosz
The rk3066 grf_soc_con0 allows interchangeable data pin
configuration for emmc and nand.
Use rockchip_nand_board_early_init function to config
nand data pins in spl as bootrom leaves it in default state.

[PATCH v1 09/17] rockchip: adc: reduce error notifications from class driver
The adc class driver reads optional "vss-supply" and
"vdd-supply" properties. The SoC adc driver can parse
for vref, so reduce error notifications when not found.

[PATCH v1 01/17] rockchip: spl: fix reloc gd and FDT blob pointer
When the Rockchip function dram_init() is called in the spl.c
board_init_f() the variable gd->ram_base returns 0.
This is problematic for functions after the gd relocation.
Fix by adding ram.base to gd->ram_base in sdram.c.
After the function spl_relocate_stack_gd is called in crt0.S
the pointer gd might be relocated and BSS with the FDT blob is erased.
The pointer gd->fdt_blob is no longer valid when
enabled SPL_OF_REAL and SPL_MMC, SPL_USB_HOST or SPL_USB_GADGET.
This patch makes that FDT properties can be parsed
in the board_init_r() function.
Fix by setting this pointers simulair to board_f.c and
copy the FDT to it's new location at the end of DRAM.

[PATCH v1 00/17] Add rk3066 ADC and USB support
Add rk3066 ADC and USB support. The Rockchip SoC rk3066 has no support for MMC and USB in the BootROM. The TPL/SPL parts are mostly stored on NAND. With U-boot stored on an external media the moment a user wants to start a recovery action it has to be done in SPL. Some boards only have one ADC switch for the user and no serial console. The U-boot USB drivers only works in combination with OF_REAL enabled. For current ARM SoCs the FDT stored in BBS is erased after SPL relocation in the crt0.S main function. So for drivers to work in SPL, FDT is move to the end of DRAM. The global_data must update there pointers. The common Rockchip functions must also become available in SPL. Most work has to be done on the ADC driver that has recently had a "upgrade" for a vref regulator. For Rockchip this regulator are mostly fixed. As we are in SPL that would introduce 2 extra U-boot classes UCLASS_REGULATOR and UCLASS_GPIO. In SPL there's no pin control yet, so reduce code and read these ADC properties from the DT in SPL. While testing some improvement had to be made for reliability. Fixup SPL compile and the way the ADC section is shown in U-boot's main menu. Add a __weak recovery button function as condition to enter the recovery mode in spl. It then looks for a boot_device to select a storage function method. And finally run the rockusb gadget while connected to a USB host. Enable all new futures by adding them to the mk808_defconfig.

[PATCH 8/9] dm: core: Add a command to show driver model statistics
This command shows the memory used by driver model along with various
hints as to what it might be if some 'core' tags were moved to use the
tag list instead of a core (i.e. always-there) pointer.
This may help with future work to reduce memory usage.

[PATCH 6/9] dm: core: Support accessing core tags
At present tag numbers are only allocated for non-core data, meaning that
the 'core' data, like priv and plat, are accessed through dedicated
functions.
For debugging and consistency it is convenient to use tags for this 'core'
data too. Add support for this, with new tag numbers and functions to
access the pointer and size for each.
Update one of the test drivers so that the uclass-private data can be
tested here.
There is some code duplication with functions like device_alloc_priv() but
this is not addressed for now. At some point, some rationalisation may
help to reduce code size, but more thought it needed on that.

This command converts pointers to addresses, but the pointers being
converted are in the image's rodata region. For sandbox this means it
is not in DRAM so it does not make sense to do this conversion.
Fix this by showing a simple pointer instead. Drop the unnecessary
@ and hex prefixes.

[PATCH 2/9] dm: core: Sort dm subcommands
Put these in alphabetic order, both in the help and in the implementation,
as there are quite a few subcommands now. Tweak the help for 'dm tree' to
better explain what it does.

[PATCH 0/9] dm: core: Support collecting and reporting stats
Driver model can use a lot of memory, as it is the core of all drivers and devices in U-Boot. Add a command to show how much is in use, along with the sizes of various data structures. This patch can be used to analyse the impact of various potential changes to driver model for SPL, none of which has been implemented. Most involve shrinking the size of struct udevice, which is a particular problem on 64-bit machines since their pointers are so unnecessarily large in SPL. To try this out, enable SPL_DM_STATS and then build and run on your board. You should see output for SPL and U-Boot proper, like this: Struct sizes: udevice 90, driver 78, uclass 30, uc_driver 78 Memory: device 11:990, device names 111, uclass a:1e0 Attached typeCount SizeCur Tags Save --- - - - - - plat 3 e0990914 7c (124) parent_plat 2 40990910 80 (128) uclass_plat 1 1099090c 84 (132) priv 613d990920 70 (112) parent_priv 0 0990908 88 (136) uclass_priv 3 38990914 7c (124) driver_data 0 0990908 88 (136) uclass 0 0 Attached total f2a5 37c (892) tags 0 0 Total size: e15 (3605) With tags: a99 (2713) - singly-linked: 901 (2305) - driver index: 88a (2186) - uclass index: 813 (2067) Drop device name (not SRAM): 111 (273) Simon Glass (9): dm: core: Rename dm_dump_all() dm: core: Sort dm subcommands dm: core: Fix addresses in the dm static command dm: core: Add documentation for the dm command dm: core: Switch the testbus driver to use a new struct dm: core: Support accessing core tags dm: core: Add a way to collect memory usage dm: core: Add a command to show driver model statistics dm: spl: Allow SPL to show memory usage cmd/dm.c| 69 -- common/spl/spl.c| 9 + doc/usage/cmd/dm.rst| 487 doc/usage/index.rst | 1 + drivers/core/Kconfig| 21 ++ drivers/core/device.c | 65 ++ drivers/core/dump.c | 79 ++- drivers/core/root.c | 53 + drivers/core/tag.c | 29 +++ drivers/misc/test_drv.c | 6 +- include/dm/device.h | 25 +++ include/dm/root.h | 45 include/dm/tag.h| 32 ++- include/dm/test.h | 7 + include/dm/util.h | 11 +- test/dm/core.c | 91 tools/dtoc/test_dtoc.py | 6 +- 17 files changed, 1004 insertions(+), 32 deletions(-) create mode 100644 doc/usage/cmd/dm.rst -- 2.36.0.512.ge40c2bad7a-goog

Migrate dm command to use U_BOOT_CMD_WITH_SUBCMDS() helper macro, to reduce
duplicated code. We can also drop the CONFIG_NEEDS_MANUAL_RELOC exception,
as the command list is updated post relocation in board_r.c initcall
initr_manual_reloc_cmdtable().

Re: [PATCH 1/5] phy: adin: remove broken support for adi,phy-mode-override
Hi Nate, Maintainers,
This patch is now superseded by Nate's
[PATCH] phy: adin: fix broken support for adi,phy-mode-override
submitted yesterday.
The remainder of this patchset cleanly applies on top of it though,
so I won't roll v2.
Let me know if there is any further feedback on this series, or if it
can be applied.

I will take a look in the coming days and see if I understand how to

I don't really mind if we fix it, or remove it - removing was the

If you prefer, I can submit a separate patch to fix it. I'll wait to
hear from you to avoid duplicated work.
I won't be able to look at this before Sunday, so feel free to work on
it.

Currently, the adin driver fails to compile.
The original patch introducing the adin driver used the function
phy_get_interface_by_name to support the adi,phy-mode-override
property. Unfortunately, a few days before the adin patch
was accepted, another patch removed support for phy_get_interface_by_name:
https://github.com/u-boot/u-boot/commit/123ca114e07ecf28aa2538748d733e2b22d8b8b5
This patch refactors adin_get_phy_mode_override, implementing the logic in
the new function, ofnode_read_phy_mode, from the patch above.
