[MTD] [NAND] S3C2410: Allow the machine code to get the BBT table from NAND
Added a flag to allow the machine code to tell the NAND subsystem that it should try to pickup a BBT from the flash, and also skip the NAND full scan at startup. Signed-off-by: Michel Pollet <buserror@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
