It looks like you're talking about u-boot, not Linux; the FCM NAND driver
has not yet been merged.  Are you using a Freescale BSP?  If so, it's
best to go through official support channels.  If you're using patches
that were recently posted, make sure you have all the bugfixes that
recently went into the linux mtd tree.
