PATCH 1/1 Updates to Korat-specific code

This patch contains updates for changes for the Korat PPC440EPx board. These changes include:

(1) Support for "permanent" and "upgradable" copies of U-Boot, as described in the new "doc/README.korat" file;

(2) a new memory map for the registers in the board's CPLD;

(3) a revised format for manufacturer's data in serial EEPROM; and

(4) changes to track updates to U-Boot for the Sequoia board.

Signed-off-by Larry Johnson <[email protected]>

---
If there is a better (or more canonical) way to generate the two versions of U-Boot for korat, I would appreciate hearing about it. I don't know enough about how "make" works for U-Boot to determine whether the method used for "sequoia" and "sequoia_nand" is appropriate.

Best regards,
Larry
