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_SOCFPGA_DWMMC
-> Enable the SOCFPGA specific driver for DesignWare SDMMC controller
