63a0afa0c3 ppc4xx: Fix problem with SDRAM init in bamboo NAND booting port
This patch fixes a problem spotted by Eugene O'Brian (thanks Eugene)
introduced by the commit:

ppc4xx/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.S

With this patch SDRAM will get initialized again and booting from NAND
is working again.

9f798766aa ppc4xx: Fixed offset of refresh rate type for Bamboo on-board DDR SDRAM
This patch also adds a note to the fixed DDR setup for Bamboo NAND booting:

Note:
As found out by Eugene O'Brien <eugene.obrien@advantechamt.com>, the fixed
DDR setup has problems (U-Boot crashes randomly upon TFTP), when the DIMM
modules are still plugged in. So it is recommended to remove the DIMM
modules while using the NAND booting code with the fixed SDRAM setup!

cf959c7d66 ppc4xx: Add NAND booting support for AMCC Bamboo (440EP) eval board
This patch adds NAND booting support for the AMCC Bamboo eval board.
Since the NAND-SPL boot image is limited to 4kbytes, this version
only supports the onboard 64MBytes of DDR. The DIMM modules can't be
supported, since the setup code for I2C DIMM autodetection and
configuration is too big for this NAND bootloader.
