nand: extend nand torture
nand torture currently works on exactly one nand block which is specified by giving the byteoffset to the beginning of the block. Extend this by allowing for a second parameter specifying the byte size to be tested. e.g. ==> nand torture 1000000 NAND torture: device 0 offset 0x1000000 size 0x20000 (block size 0x20000) Passed: 1, failed: 0 ==> nand torture 1000000 40000 NAND torture: device 0 offset 0x1000000 size 0x40000 (block size 0x20000) Passed: 2, failed: 0 Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> Reviewed-by: Benoît Thébaudeau <benoit.thebaudeau.dev@gmail.com> [scottwood: fix usage to show size as optional, and add misssing braces] Signed-off-by: Scott Wood <oss@buserror.net>
