[U-Boot] [PATCH v2 1/4] mx6qsabreauto: Configure the WEIM controller like the kernel

[U-Boot] [PATCH v2 1/4] mx6qsabreauto: Configure the WEIM controller like the kernel

[Fabio Estevam]

Do the same WEIM initialization as done in the Linux kernel
according to arch/arm/boot/dts/imx6qdl-sabreauto.dtsi from kernel 4.9.

[U-Boot] [PATCH v2 2/4] mx6qsabreauto: Pass the correct parallel NOR width

[Fabio Estevam]

On mx6qsabreauto the parallel NOR width is 16 bits, so pass configure
CONFIG_SYS_FLASH_CFI_WIDTH correctly so that the CFI driver does not
use 8 bits by default.

[U-Boot] [PATCH v2 3/4] Kconfig: Move USE_ARCH_MEMCPY/MEMSET to Kconfig

[Fabio Estevam]

Move USE_ARCH_MEMCPY/MEMSET options to Kconfig.

Make it "default y" for the ARM architecture.

Unset these options for uniphier and tegra to preserve the original
behavior.

[U-Boot] [PATCH v2 4/4] cmd: mem: Use memcpy for 'cp' command

[Fabio Estevam]

Simplify the 'cp' command implementation by using the memcpy() function,
which brings the additional benefit of performance gain for those who have
CONFIG_USE_ARCH_MEMCPY selected.

Tested on a mx6qsabreauto board where a 5x gain in performance is seen
when reading 10MB from the parallel NOR memory.

Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com>

Changes since v1:
- Always use memcpy()

[U-Boot] [PATCH v2 3/4] Kconfig: Move USE_ARCH_MEMCPY/MEMSET to Kconfig

So, thanks for starting on this.  But it needs to go into
arch/arm/Kconfig.  And I meant, it should be default y if CPU_V7, and
depend on !ARM64 (because we don't have asm versions of these functions,
we could borrow them from the kernel, and someone should I suspect).
The key here is that on some older ARM cores we will exceed the SPL size
limit with these functions enabled.  Make sense?  Thanks!

Can you load up a few other platforms via QEMU and test it out there?
Thanks!

I feel like this is correct.  I also feel like it's too close to release
to do this, so I'll be applying this shortly after release, thanks!

I also found it odd, and might try and rectify, that we don't have a
'cp' test in test.py which would make being relatively sure it's OK on
x86/MIPS/PowerPC easy, slightly less easy (I'll be firing up qemu by
hand and maybe writing a test too).

Yes, yes it would, thanks for the reminder.  I'm kicking off a round of
testing in travis-ci now along with another pre-req of finally, really,
making arch/arm/lib/mem{set,cpy}.S be used by default in most cases.

This is orthogonal to the other patches in the series, and it was not
yet applied.

Applied to u-boot-imx, thanks !
