current U-Boot shows on startup (for example on the enbw_cmc board) the following printfs from the nand subsystem:

Flash: 2 MiB NAND: Bad block table found at page 65472, version 0x01 Bad block table found at page 65408, version 0x01 nand_read_bbt: Bad block at 0x000002980000 nand_read_bbt: Bad block at 0x000003240000 128 MiB MMC: davinci: 0

remove them to debug output, so it shows with this patch:

Flash: 2 MiB NAND: 128 MiB MMC: davinci: 0
