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

  24           Driver model provides a means of supporting device operations. This
  25           option moves MMC operations under the control of driver model. The
  26           option will be removed as soon as all DM_MMC drivers use it, as it
  27           will the only supported behaviour.

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

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

  48           Enables support for SDHCI 2.0 controller present on some Qualcomm
  49           Snapdragon devices. This device is compatible with eMMC v4.5 and
  50           SD 3.0 specifications. Both SD and eMMC devices are supported.
  51           Card-detect gpios are not supported.

  57           This enables support for the Atmel SDHCI controller, which supports
  58           the embedded MultiMedia Card (e.MMC) Specification V4.51, the SD
  59           Memory Card Specification V3.0, and the SDIO V3.0 specification.
  60           It is compliant with the SD Host Controller Standard V3.0
  61           specification.

  67           This enables support for the Rockchip SD/MMM controller, which is
  68           based on Designware IP. The device is compatible with at least
  69           SD 3.0, SDIO 3.0 and MMC 4.5 and supports common eMMC chips as well
  70           as removeable SD and micro-SD cards.

 109           other than allow sandbox to be build with MMC support. This
 110           improves build coverage for sandbox and makes it easier to detect
 111           MMC build errors with sandbox.
