Storing the environment in the NAND is also an option, as you can see in the
board configuration.

So I guess all the other at91-based boards need fixing too ? They don't seem to
do that.

I'm not sure what you mean. There's no dataflash on this board. From what I can
see, 1 << 1 is required to set the PC5 pin on the B peripheral controller, and
PC5 happens to be the chip select pin for the on-board SPI EEPROM. Am I missing
something here ?
