58	help
59	  Enable MMC framework tinification support. This option is useful if
60	  if your SPL is extremely size constrained. Heed the warning, enable
61	  this option if and only if you know exactly what you are doing, if
62	  you are reading this help text, you most likely have no idea :-)
63
64	  The MMC framework is reduced to bare minimum to be useful. No malloc
65	  support is needed for the MMC framework operation with this option
66	  enabled. The framework supports exactly one MMC device and exactly
67	  one MMC driver. The MMC driver can be adjusted to avoid any malloc
68	  operations too, which can remove the need for malloc support in SPL
69	  and thus further reduce footprint.
