config MMC
	bool "MMC/SD/SDIO card support"
	default ARM || PPC || SANDBOX
	help
	  This selects MultiMediaCard, Secure Digital and Secure
	  Digital I/O support.

	  If you want MMC/SD/SDIO support, you should say Y here and
	  also to your specific host controller driver.

config DM_MMC
	bool "Enable MMC controllers using Driver Model"
	depends on DM
	help
	  This enables the MultiMediaCard (MMC) uclass which supports MMC and
	  Secure Digital I/O (SDIO) cards. Both removable (SD, micro-SD, etc.)
	  and non-removable (e.g. eMMC chip) devices are supported. These
	  appear as block devices in U-Boot and can support filesystems such
	  as EXT4 and FAT.

config DM_MMC_OPS
	bool "Support MMC controller operations using Driver Model"
	depends on DM_MMC
	default y if DM_MMC
	help
	  Driver model provides a means of supporting device operations. This
	  option moves MMC operations under the control of driver model. The
	  option will be removed as soon as all DM_MMC drivers use it, as it
	  will the only supported behaviour.

if MMC

config SPL_MMC_TINY
	bool "Tiny MMC framework in SPL"
	help
	  Enable MMC framework tinification support. This option is useful if
	  if your SPL is extremely size constrained. Heed the warning, enable
	  this option if and only if you know exactly what you are doing, if
	  you are reading this help text, you most likely have no idea :-)

	  The MMC framework is reduced to bare minimum to be useful. No malloc
	  support is needed for the MMC framework operation with this option
	  enabled. The framework supports exactly one MMC device and exactly
	  one MMC driver. The MMC driver can be adjusted to avoid any malloc
	  operations too, which can remove the need for malloc support in SPL
	  and thus further reduce footprint.

	depends on DM_MMC && BLK && DM_MMC_OPS
	depends on MMC_SDHCI
	help
