[U-Boot] [PATCH 2/3] pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

2017-10-16 Thread Masahiro Yamada

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

  lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
  lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

[U-Boot] [PATCH 1/3] dtc: libfdt: import fdt_addresses.c and fdt_overlay.c

2017-10-16 Thread Masahiro Yamada

I will move the pylibfdt build script under the scripts/dtc/ in the
next commit.  We need two more files to build the pylibfdt.

We have almost same copies in lib/libfdt, but we are collecting all
DTC-derived files into scripts/dtc.

Import fdt_addresses.c and fdt_overlay.c from DTC v1.4.5.

[U-Boot] [PATCH 3/3] pylibfdt: compile pylibfdt only when dtoc/binman is necessary

2017-10-16 Thread Masahiro Yamada

Currently, pylibfdt is always compiled if swig is installed on your
machine.  It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.

"checkbinman" and "checkdtoc" are wrong.  It is odd that the final
build stage checks if we have built necessary tools.  If your platform
depends on dtoc/binman, you must be able to build pylibfdt.  If swig
is not installed, it should fail immediately.

I added PYLIBFDT, DTOC, BINMAN entries to Kconfig.  They should be
property select:ed by platforms that need them.  Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

Has Rob's patch to re-sync the kernel with v1.4.5-and-change been
applied?  Moving forward I'd like to try and keep us in-sync with the
version the kernel is using (we're ahead of the kernel until that change
goes in, and then I think behind).  Thanks!

[U-Boot] [ANN] U-Boot v2017.11-rc2 released

2017-10-16 Thread Tom Rini

Hey all,

It's release day and v2017.11-rc2 is out.  I'm mostly happy with the
size of the changes here and I did remember to sync the defconfigs prior
to tagging.

At this point, any changes that come in need to be clear fixes to a
problem or Kconfig migrations that can be shown as correct.

I hope that this release will migrate over to the FTP server, we shall
see shortly.

Things look on track for -rc3 on the 30th of October and -rc4 on the 6th
of November.  Thanks all!

No, no it wasn't, bad me for not cleaning that out of my bundle after
noticing it wasn't applicable and skipping it.

Re: [U-Boot] Silencing SPL output

This is probably something of a foot-gun but here we go...

I was wondering if it's worth providing the ability to silence the
output from the SPL. CONFIG_SILENT_CONSOLE exist for u-boot proper but
the SPL preloader_console_init bypasses anything that would set
GD_FLG_SILENT. Even if it didn't the SPL probably doesn't have access
to any environment that would allow it to be set/unset.

I was thinking about adding a SPL specific CONFIG option that would
set GD_FLG_SILENT (probably in spl_init). Aside from re-compiling
there wouldn't be any way of making the SPL loud. Is this a reasonable
idea or is it just asking for boards to be bricked with no way of
telling what went wrong?



I have a at91 based board in mainline, which has no SPL output
enabled (as there is no space for it), see:

configs/smartweb_defconfig

Do not define
CONFIG_SPL_SERIAL_SUPPORT=y



Thanks for the tip. Unfortunately disabling  CONFIG_SPL_SERIAL_SUPPORT
causes some build errors (at least for db-88f6820-amc)

   common/spl/built-in.o: In function `preloader_console_init':
common/spl/spl.c:463: undefined reference to `serial_init' >lib/built-in.o:

`spi_flash_probe_bus_cs':drivers/mtd/spi/sf-uclass.c:66: undefined
reference to `snprintf'
   scripts/Makefile.spl:358: recipe for target 'spl/u-boot-spl' failed

The first one looks like an appropriate #ifdef (or do/while fallback)
is missing. The others look like missing dependencies.


Yes, this has to be fixed for your arch, see for example at91:

http://git.denx.de/?p=u-boot.git;a=blob;f=arch/arm/mach-at91/spl_at91.c;h=cc3341acb537c4b4edf3a241f386a44c40220c9f;hb=eb0044db392247aa1c43e29f2703418d5668018a#l124

Or may better, we should fix this in common/spl/spl.c

Hmm... error in "drivers/mtd/spi/sf-uclass.c" is strange:

code:
#if defined(CONFIG_SPL_BUILD) && defined(CONFIG_USE_TINY_PRINTF)
str = "spi_flash";
#else
char name[30];

snprintf(name, sizeof(name), "spi_flash@%d:%d", busnum, cs);
str = strdup(name);
#endif

You are sure you build for SPL ?


I was already on the fence about silencing SPL output so I'm not
planning on pursuing it. I thought I'd mention the build failures in
case someone wants to take a look.


Ah, Okay.

Heiko

fdt_addresses.c and fdt_overlay.c in linux-next
are already synced with DTC 1.4.5

I will do re-sync just in case, but those two files will not change.

[U-Boot] [PATCH v2 3/4] pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

2017-10-16 Thread Masahiro Yamada

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

  lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
  lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

[U-Boot] [PATCH v2 4/4] pylibfdt: compile pylibfdt only when dtoc/binman is necessary

2017-10-16 Thread Masahiro Yamada

Currently, pylibfdt is always compiled if swig is installed on your
machine.  It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.

"checkbinman" and "checkdtoc" are wrong.  It is odd that the final
build stage checks if we have built necessary tools.  If your platform
depends on dtoc/binman, you must be able to build pylibfdt.  If swig
is not installed, it should fail immediately.

I added PYLIBFDT, DTOC, BINMAN entries to Kconfig.  They should be
property select:ed by platforms that need them.  Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

 A flush of the cache is required before any outbound DMA access can
 take place. The minimum size that can be flushed from the cache is
 one cache line size. Therefore, any buffer allocated for DMA should
 be in multiples of cache line size.

 Thus, allocate memory for ep0_trb in multiples of cache line size.

 Also, when local variable trb is assigned to dwc->ep0_trb[1] and used
 to flush cache, it leads to cache misaligned messages as only the base
 address dwc->ep0_trb is cache aligned.

 Therefore, flush cache using ep0_trb_addr which is always cache 
 aligned.

 then that's what should be fixed. No?
