This patch changes nand_wait_ready() to not just call nand_wait(), since this will send a new command to the NAND chip. We just want to wait for the chip to become ready here.
Signed-off-by: Stefan Roese sr@denx.de --- William & Stig, could you please review this patch and test it on your platforms?
Thanks.
