[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.

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

Applied to u-boot-imx, thanks !

[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.

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!

[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.

Changes since v1:
- Always use memcpy()

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).

Is it a good time to apply this one now?

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.
