  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

  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
