mmc: Adding AUTO_BKOPS_EN bit set for Auto BKOPS support
Adding dedicated flag for AUTO_BKOPS in card->ext_csd structure. Read AUTO_BKOPS bit value from the device EXT_CSD and set to the card->ext_csd structure. In mmc_decode_ext_csd() add a print message in case the AUTO_BKOPS is enabled Signed-off-by: Uri Yanai <uri.yanai@sandisk.com> Signed-off-by: Alex Lemberg <alex.lemberg@sandisk.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
