[U-Boot] [PATCH 0/6] SPL: Port SPL framework to powerpc

[Stefan Roese]

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 3rd 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
