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
