23 Read the bad block table by searching for a given ident pattern. Search
24 is preformed either from the beginning up or from the end of the device
25 downwards. The search starts always at the start of a block. If the
26 option NAND_BBT_PERCHIP is given, each chip is searched for a bbt,
27 which contains the bad block information of this chip. This is
28 necessary to provide support for certain DOC devices.

30 The bbt ident pattern resides in the oob area of the first page in a
31 block.
