Add support of 2 stage NAND, SD, SPI boot loader using SPL framework.
here, PBL initialise the internal SRAM and copy SPL(160KB). This further
initialise DDR using SPD and environment and copy u-boot(768 KB) from NAND to DDR.
Finally SPL transer control to u-boot.

Initialise/create followings required for SPL framework
       - Add spl.c which defines board_init_f, board_init_r
       - update tlb and ddr accordingly

^^^^^^^^
Don't you need a separate RCW setting for SPI?
The previous patchset had a note about it.

That's a "Wait" command.
Unless the "Flush" was command (that is in most PBI files I've read, 
Flush/Wait pait) was inadvertantly deleted.

You can change.
Generally switch has higher precedence over  PBI_SRC in RCW.

Flush command only work for CCSRBAR address space. It should not be used 
for CPC-SRAM.

This is the reason, it has been removed.

Does this affect all mpc85xx cores?

I've noticed this same weird behavior on a T1040QDS.
A simple write to CPC-SRAM before a Flush command causes the LEDs to report 
an error. 
i.e
89ffff00 4bfff004
09138000 00000000
091380c0 00000001

After putting the CPC-SRAM write after the Flush the write was successful 
(as verified by a BDI-3000).
i.e
09138000 00000000
091380c0 00000001
89ffff00 4bfff004
091380c0 00000001


BUT it seems this does not occur on the P5040DS. The P5040DS_SPIFLASH 
creates a u-boot that has Flush commands and it boots correctly.
[local]$ xxd -g4 obj-P5040DS_SPIFLASH/u-boot.pbl
:
00cc0a0: ffffffff 81ffffc0 ffffffff ffffffff  ................
00cc0b0: ffffffff ffffffff ffffffff ffffffff  ................
00cc0c0: ffffffff ffffffff ffffffff ffffffff  ................
00cc0d0: ffffffff ffffffff ffffffff ffffffff  ................
00cc0e0: ffffffff 4bfff004 09138000 00000000  ....K...........
00cc0f0: 091380c0 00000000 08138040 aa69eb89  ...........@.i..



On another note, if this affects all mpc85xx cores then I guess 
tools/pblimage.c needs updating. The add_end_cmd() always adds a Flush 
command prior to a CRC check (CONT=0) command.
