config FS_JFFS2
bool "Enable JFFS2 filesystem support"
help
This provides support for reading images from JFFS2 (Journalling
Flash File System version 2). JFFS2 is a log-structured file system
for use with flash memory devices. It supports raw NAND devices,
hard links and compression.
config JFFS2_LZO
bool "Enable LZO compression in JFFS2"
depends on FS_JFFS2
help
Enable LZO compression in the JFFS2 filesystem
config JFFS2_NAND
bool "Enable JFFS2 support for NAND flash"
depends on FS_JFFS2
help
Enable support for NAND flash as the backing store for JFFS2.
config SYS_JFFS2_SORT_FRAGMENTS
bool "Enable JFFS2 sorting of filesystem fragments (SLOW!)"
depends on FS_JFFS2
help
If you boot from a partition which is mounted writable, and you
update your boot environment by replacing single files on that
partition, you should also define CONFIG_SYS_JFFS2_SORT_FRAGMENTS.
Scanning the JFFS2 filesystem takes *much* longer with this feature,
though. Sorting is done while inserting into the fragment list,
which is more or less a bubble sort. That algorithm is known to be
O(n^2), thus you should really consider if you can avoid it!
