mmc: retry CMD1 in mmc_send_op_cond() until the eMMC is ready According to eMMC specification v5.1 section 6.4.3, we should issue CMD1 repeatedly in the idle state until the eMMC is ready even if mmc_send_op_cond() send CMD1 with argument = 0. Otherwise some eMMC devices seems to enter the inactive mode after mmc_complete_op_cond() issued CMD0 when the eMMC device is busy.
