[ARM] 4469/1: ANUBIS: large page NAND support
Add support for the partition layour used on the revision B modules which ship with large page NAND flash as default. The differnce between the old and new layouts is that the large page devices use 128KiB blocks, so the initial loader partition now ends at 128KiB boundary pushing the begining of partition 1 up. The rest of the partitions are in the same place as the small page NAND devices. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
