460EX doesn't support a fixed bootstrap option to boot from 512 byte page NAND devices. The only bootstrap option for NAND booting is option F for 2k page devices. So to boot from a 512 bype page device, the I2C bootstrap EEPROM needs to be programmed accordingly. This patch adds basic NAND booting support for the AMCC Canyonlands aval board and also adds support to the "bootstrap" command, to enable NAND booting I2C setting. Tested with 512 byte page NAND device (32MByte) on Canyonlands. Signed-off-by: Stefan Roese <sr@denx.de>
