[U-Boot] [PATCH v2 0/12] 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 4th 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!

Note: I switched to using patman with this 2nd patchset version.
Hopefully I didn't screw too much up with this.

Tom, I would prefer, if you could merge some of those patches into
your SPL rework series. Perhaps those first 6 patches once we agree
on them?

  SPL: Fix build problems on ARM with new SPL framework
  SPL: Use image_get_xxx() functions to access header values
  SPL: Add option to skip copying of the mkimage header
  SPL: Add NOR flash booting support
  powerpc: Extract EPAPR_MAGIC constants into processor.h
  SPL: Port SPL framework to powerpc

What do you think?

Thanks,
Stefan

Changes in v2:
- Add option to skip copying of the mkimage header
- Rebased on Tom's SPL framework patches v4
- a3m071 build: Concat SPL binary and u-boot.img directly (no padding)
