MTD-backed ROM file system support


RomFS backing stores
└─>MTD-backed ROM file system support
In linux kernel since version 2.6.30 (release Date: 2009-06-09)  
This permits ROMFS to use MTD based devices directly, without the
intercession of the block layer (which may have been disabled). It
also allows direct mapping of MTD devices through romfs files under
NOMMU conditions if the underlying device is directly addressable by
the CPU.

If unsure, answer Y.
