[U-Boot] [PATCH v5 00/13] split tegra20 arm7 code into separate SPL

[Marek Vasut]

Dear Allen Martin,

> This patch series fixes a long standing problem with the tegra20
> u-boot build.  Tegra20 contains an ARM7TDMI boot processor and a
> Cortex A9 main processor.  Prior to this patch series this was
> accomplished by #ifdefing out any armv7 code from the early boot
> sequence and creating a single binary that runs on both both the
> ARM7TDMI and A9.  This was very fragile as changes to compiler options
> or any additions or rearranging of the early boot code could add
> additional armv7 specific code causing it to fail on the ARM7TDMI.
> 
> This patch series pulls all the armv4t code out into a separate SPL
> that does nothing more than initialize the A9 and transfer control to
> it.  The resultint SPL and armv7 u-boot are concatenated together into
> a single image.

I'm really glad to see nvidia contributing to uboot.

It's a real pity it's not the same at the field of desktop graphics, my laptop 
is suffering badly because of that :-(

Best regards,
