The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

Alternative SDRAM settings:

#define SDRAM_EMODE 0x40090000
|

#define SDRAM_CONTROL 0x715f0f00

/* Settings for XLB = 99 MHz */

The board ships default with the environment in EEPROM
|

Moving the environment to flash can be more reliable
