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
