  5           This is a very small read-only file system mainly intended for
  6           initial ram disks of installation disks, but it could be used for
  7           other read-only media as well.  Read
  8           <file:Documentation/filesystems/romfs.txt> for details.
  9 
 10           To compile this file system support as a module, choose M here: the
 11           module will be called romfs.  Note that the file system of your
 12           root partition (the one containing the directory /) cannot be a
 13           module.

 30         depends on BLOCK
 31         help
 32           This permits ROMFS to use block devices buffered through the page
 33           cache as the medium from which to retrieve data.  It does not allow
 34           direct mapping of the medium.

 40         depends on MTD=y || (ROMFS_FS=m && MTD)
 41         help
 42           This permits ROMFS to use MTD based devices directly, without the
 43           intercession of the block layer (which may have been disabled).  It
 44           also allows direct mapping of MTD devices through romfs files under
 45           NOMMU conditions if the underlying device is directly addressable by
 46           the CPU.
