2 tristate "ROM file system support"
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.
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
15 If you don't know whether you need it, then you don't need it:
19 bool "Block device-backed ROM file system support" if (ROMFS_ON_MTD && EMBEDDED)
20 depends on ROMFS_FS && BLOCK
22 This permits ROMFS to use block devices buffered through the page
23 cache as the medium from which to retrieve data. It does not allow
24 direct mapping of the medium.
29 bool "MTD-backed ROM file system support"
31 depends on MTD=y || (ROMFS_FS=m && MTD)
33 This permits ROMFS to use MTD based devices directly, without the
34 intercession of the block layer (which may have been disabled). It
35 also allows direct mapping of MTD devices through romfs files under
36 NOMMU conditions if the underlying device is directly addressable by
