CONFIG_SOCFPGA_DWMMC_FIFO_DEPTH is defined in the socfpga_common.h, but not referenced at all. Remove. Also, clean-up the README.socfpga. CONFIG_MMC should not be defined in the header since it was moved to Kconfig by commit c2726995 ("mmc: complete unfinished move of CONFIG_MMC"). I see no grep hit for the others. Signed-off-by:

Here are macro and detailed configuration required to enable DesignWare SDMMC
controller support within SOCFPGA
#define CONFIG_GENERIC_MMC
-> Enable the generic MMC driver
#define CONFIG_SYS_MMC_MAX_BLK_COUNT 256
-> Using smaller max blk cnt to avoid flooding the limited stack in OCRAM
#define CONFIG_DWMMC
-> Enable the common DesignWare SDMMC controller framework
#define CONFIG_SOCFPGA_DWMMC
-> Enable the SOCFPGA specific driver for DesignWare SDMMC controller
