This patch adds a board command to configure the I2C bootstrap EEPROM
values. Right now 533 and 667MHz are supported for booting either via NOR
or NAND FLASH. Here the usage:
=> bootstrap 533 nor ;to configure the board for 533MHz NOR booting
=> bootstrap 667 nand ;to configure the board for 667MHz NNAND booting
