Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS. This is necessary for the assembly-language code that relocates CCSR, since the assembler does not understand 64-bit constants.
CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it should not be defined in a board header file. Similarly, CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so it should also not be defined in the board header file.
CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT, and so CCSR will not be relocated.
Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot builds (e.g. NAND) are required to relocate CCSR only during the last stage (i.e. the "real" U-Boot). All other stages should define CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.
README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

Why didn't we do in include/mpc85xx.h:
#ifndef CONFIG_SYS_CCSRBAR_PHYS_LOW #define CONFIG_SYS_CCSRBAR_PHYS_LOW CONFIG_SYS_CCSRBAR #endif
Thus removing that line from every board file?
