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 c27269953b
("mmc: complete unfinished move of CONFIG_MMC"). I see no grep hit
for the others.

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
