15	depends on DM
16	help
17	  This enables the MultiMediaCard (MMC) uclass which supports MMC and
18	  Secure Digital I/O (SDIO) cards. Both removable (SD, micro-SD, etc.)
19	  and non-removable (e.g. eMMC chip) devices are supported. These
20	  appear as block devices in U-Boot and can support filesystems such
21	  as EXT4 and FAT.

36config SPL_MMC_TINY
37	bool "Tiny MMC framework in SPL"
38	help
39	  Enable MMC framework tinification support. This option is useful if
40	  if your SPL is extremely size constrained. Heed the warning, enable
41	  this option if and only if you know exactly what you are doing, if
42	  you are reading this help text, you most likely have no idea :-)
43
44	  The MMC framework is reduced to bare minimum to be useful. No malloc
45	  support is needed for the MMC framework operation with this option
46	  enabled. The framework supports exactly one MMC device and exactly
47	  one MMC driver. The MMC driver can be adjusted to avoid any malloc
48	  operations too, which can remove the need for malloc support in SPL
49	  and thus further reduce footprint.
