You don't actually need to define this to have a value.
+#define CONFIG_DWMMC +#define CONFIG_SOCFPGA_DWMMC +#define CONFIG_SOCFPGA_DWMMC_FIFO_DEPTH 1024 +#define CONFIG_SOCFPGA_DWMMC_DRVSEL 3 +#define CONFIG_SOCFPGA_DWMMC_SMPSEL 0 +#define CONFIG_BOUNCE_BUFFER +/* using smaller max blk cnt to avoid flooding the limited stack we have */ +#define CONFIG_SYS_MMC_MAX_BLK_COUNT 256
This is something I am wondering about (btw. you might have seen a FIXME tag in my repository right next to this code). Do we really need this in U-Boot or is this portion SPL specific ? Or do we even need this limit at all ? [...]
Anyway, I will pick them in my tree and add a bit more magic sause to them , then re-post the whole series.
Best regards, Marek Vasut
