64852d09e0 ppc4xx/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.S
This patch consolidates the 405 and 440 parts of the NAND booting code
selected via CONFIG_NAND_SPL. Now common code is used to initialize the
SDRAM by calling initdram() and to "copy/relocate" to SDRAM/OCM/etc.
Only *after* running from this location, nand_boot() is called.

Please note that the initsdram() call is now moved from nand_boot.c
to start.S. I experienced problems with some boards like Kilauea
(405EX), which don't have internal SRAM (OCM) and relocation needs to
be done to SDRAM before the NAND controller can get accessed. When
initdram() is called later on in nand_boot(), this can lead to problems
with variables in the bss sections like nand_ecc_pos[].

42be56f53c NAND: Add ECC support to NAND booting support in nand_spl/nand_boot.c
The U-Boot NAND booting support is now extended to support ECC
upon loading of the NAND U-Boot image.

Tested on AMCC Sequoia (440EPx) and Bamboo (440EP).

887e2ec9ec Add support for AMCC Sequoia PPC440EPx eval board
- Add support for PPC440EPx & PPC440GRx
- Add support for PPC440EP(x)/GR(x) NAND controller
  in cpu/ppc4xx directory
- Add NAND boot functionality for Sequoia board,
  please see doc/README.nand-boot-ppc440 for details
- This Sequoia NAND image doesn't support environment
  in NAND for now. This will be added in a short while.
