[U-Boot] [PATCH v4 0/7] 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 is based
on the current "next" branch.

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 v4:
- Build spl.o only for SPL image
- getenv_f not extracted into separate file. Only Makefile
  additions for SPL_BUILD needed.
- Add remark to call "fdt chosen" to board/a3m071/README
- Configure PCS2 as CODEC2 (SPI)
- Drop patch fdt: cmd_fdt: Call fdt_chosen() from "fdt boardsetup"

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)

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)
