Subject: [U-Boot] [PATCH v5 00/13] split tegra20 arm7 code into separate SPL
Date: Tue, 26 Jun 2012 03:53:29 +0200 [thread overview]

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.

> 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,
