-The current NAND implementation is based on what is in recent
-Linux kernels.  The old legacy implementation has been removed.

-If you have board code which used CONFIG_NAND_LEGACY, you'll need

 The Disk On Chip driver is currently broken and has been for some time.
 There is a driver in drivers/mtd/nand, taken from Linux, that works with
 the current NAND system but has not yet been adapted to the u-boot
