Hi Anton,
I tried reenabling CONFIG_MTD_NAND_FSL_UPM in the Fedora kernel
today (currently on 2.6.27-rc9-git1), and got the error below.

ERROR: "fsl_lbc_lock" [drivers/mtd/nand/fsl_upm.ko] undefined!

It seems that this isn't exported to modules.
diff below fixes this. (Not tested yet, the Fedora ppc
builders are a little slow).

CONFIG_MTD_NAND_FSL_UPM can be built modular, but needs to
use fsl_lbc_lock, which isn't currently exported.
