| 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 |
