  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 :-)

  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.
