ppc4xx: 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 <lrj@acm.org>
