Cover letter [U-Boot] [PATCH v5 00/13] split tegra20 arm7 code into separate SPL
Quoted 18 lines · 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.

Changes:
v5:
- added missing mkdir rules in all tegra20 board Makefiles that include common code and changed them to be unconditional
- make new u-boot-dtb-t2.bin rule default for tegra20 and copy resulting binary over u-boot.bin
Doesn't that then destroy the original u-boot.bin so it can't be inspected?
