OMAP2PLUS and BCM283X mmc controllers do not work correctly with new emmc code which reads partition access bits prior mmc controller reset.
So introduce a new config option MMC_ENABLE_PART_ACCESS, which is by default disabled for ARCH_OMAP2PLUS and ARCH_BCM283X; and selected for 32-bit mvebu mmc booting (which requires it).

Read partition access bits from partition config register before card reset commandbecause these bits are reset to default value (User Data Area) during card reset.This allows us to preserve original value of partition access bits used by the codewhich loaded us (for example BootROM) and use it for board specific boot purposes..This is required when U-Boot is using EXT_CSD_EXTRACT_PARTITION_ACCESS macro.config SUPPORT_EMMC_RPMB bool "Support eMMC replay protected memory block (RPMB)" imply CMD_MMC_RPMB diff --git a/drivers/mmc/mmc.c b/drivers/mmc/mmc.c index 9915610d82b1..fa3c4d1937c1 100644 --- a/drivers/mmc/mmc.c +++ b/drivers/mmc/mmc.c @@ -2864,6 +2864,7 @@ int mmc_get_op_cond(struct mmc *mmc, bool quiet) retry: mmc_set_initial_state(mmc);
