- *     Disable the RTEMS filesystems. You get an empty DEVFS.
- *
- *   - CONFIGURE_USE_DEVFS_AS_BASE_FILESYSTEM:

- *   - CONFIGURE_FILESYSTEM_ALL:
- *     Add file filesystems to the default filesystem table.
- *
- *   List of available file systems. You can define as many as you like:
- *     - CONFIGURE_FILESYSTEM_IMFS   - In Memory File System (IMFS)
- *     - CONFIGURE_FILESYSTEM_DEVFS  - Device File System (DSVFS)
- *     - CONFIGURE_FILESYSTEM_TFTPFS - TFTP File System, networking enabled
- *     - CONFIGURE_FILESYSTEM_FTPFS  - FTP File System, networking enabled
- *     - CONFIGURE_FILESYSTEM_NFS    - Network File System, networking enabled
- *     - CONFIGURE_FILESYSTEM_DOSFS  - DOS File System, uses libblock
- *     - CONFIGURE_FILESYSTEM_RFS    - RTEMS File System (RFS), uses libblock
- *     - CONFIGURE_FILESYSTEM_JFFS2  - Journalling Flash File System, Version 2
- *
- *   Combinations:
- *
- *    - If nothing is defined the base file system is the IMFS.
- *
- *    - If CONFIGURE_APPLICATION_DISABLE_FILESYSTEM is defined all filesystems
- *      are disabled by force.
- *
- *    - If CONFIGURE_USE_DEVFS_AS_BASE_FILESYSTEM is defined all filesystems
- *      are disabled by force and DEVFS is defined.
