mmc: fsl_esdhc: Add new config option for default fallback mode
Currently default fallback SDHC mode is 1-bit. Add new config option CONFIG_SYS_FSL_ESDHC_DEFAULT_BUS_WIDTH to allow specifying default fallback mode. This is useful e.g. for SPL builds which loads other parts from SD card during boot process. Signed-off-by: Pali Rohár <pali@kernel.org> Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com>
