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.
This patch series is also available from: git://github.com/arm000/u-boot.git branch: tegra-spl-v10
Changes: v10:
- added fix to MAKEALL script so that it correctly parses new boards.cfg
I applied this to u-boot-tegra/master and pushed the new code upstream. The pull request remains the same (except for the inclusion of the MAKEALL patch, of course). I can send a new one if required - please let me know.
Currently running a ./MAKEALL arm - I assume it'll complete w/o errors (except for the ohci-hcd.c warnings I mentioned previously that are not due to this patch series).
Are you going to refresh the next branch anytime soon or are you planing on doing this once the master branch is merged to arm/master?
Thanks, Lucas
