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

31	help
32	  Driver model provides a means of supporting device operations. This
33	  option moves MMC operations under the control of driver model. The
34	  option will be removed as soon as all DM_MMC drivers use it, as it
35	  will the only supported behaviour.

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