           If you don't know whether you need it, then you don't need it:
           answer N.

+config ROMFS_ON_BLOCK
+        bool "Block device-backed ROM file system support" if (ROMFS_ON_MTD && EMBEDDED)
+        depends on ROMFS_FS && BLOCK
+        help
+          This permits ROMFS to use block devices buffered through the page
+          cache as the medium from which to retrieve data.  It does not allow
+          direct mapping of the medium.
+
+          If unsure, answer Y.

+config ROMFS_ON_MTD
+        bool "MTD-backed ROM file system support"
+        depends on ROMFS_FS
+        depends on MTD=y || (ROMFS_FS=m && MTD)
+        help
+          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.
