uboot-nand-markbad-reallybad.patch

Uboot常用的移植patches, 方便定制移植到s3c2440

This patch makes sure that the 'nand markbad' command does not only mark a block
'bad' in the bad-block table, but _also_ marks it bad in the OOB area.

we need this to preserve the bad block status when re-creating the bad block table
at some later point.
