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.
