This patchset ports the SPL framework to powerpc. Its based on the SPL generalization lately done by Tom Rini. The patches can be applied on top of his 7th version located here:
http://github.com/trini/u-boot WIP/spl-improvements
Additionally, a new MPC5200 board port is included, the a3m071 board port. This board port uses this SPL framework mainly to speed up booting into the OS (Linux of course). Detection of Linux vs. U-Boot booting is done here by checking the environment variable "boot_os". If "boot_os" is set to "yes", then the OS (Linux) is booted. Otherwise the "real" U-Boot is booted. For this env checking in the SPL, a small restructuring of the env code has been done.
Comments welcome!
Thanks, Stefan
Changes in v2: - Rebased on Tom's SPL framework patches v4 - Add option to skip copying of the mkimage header - Rebased on Tom's SPL framework patches v4 - Rebased on Tom's SPL framework patches v4 - a3m071 build: Concat SPL binary and u-boot.img directly (no padding)
Changes in v3: - Rebased on current master plus SPL framework v7 - Don't use special MPC5xxx memcpy in SPL - Move linker symbols to header spl.h (checkpatch)
