mmc: block: add fixup of broken CMD23 for Sandisk card
Some Sandisk cards(such as "SDMB-32" and "SDM032" cards) can't support CMD23, and would generate CMD timeout. So add FIX-UP for these two types Sandisk cards. Error log: mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900 mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900 mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900 end_request: I/O error, dev mmcblk0, sector 0 Buffer I/O error on device mmcblk0, logical block 0 mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900 Signed-off-by: Yangbo Lu <yangbo.lu@freescale.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
