[U-Boot] SPI and I2C EEPROM

Hi all,

On one of our new boards we have both a SPI (M9256-W) and I2C (24lc256) 
EEPROM. I have run into a couple of issues. First of all, it looks like 
the eeprom command can only handle one EEPROM device. It would be useful 
if multiple devices could be supported.

Another issue I ran into is that the M95XXX driver is hard coded to use CS1.

Perhaps the eeprom command could be enhanced to specify whether the 
device should be spi or i2c rather than hard coded as well as support 
multiple devices?

-Aaron
