JFFS2 in U-Boot is a read only implementation of the file system in
-Linux with the same name. To use JFFS2 define CFG_CMD_JFFS2.
+Linux with the same name. To use JFFS2 define CONFIG_CMD_JFFS2.
The module adds three new commands.
fsload - load binary file from a file system image
fsinfo - print information about file systems
ls - list files in a directory
+chpart - change active partition
+
+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 CFG_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!
There is two ways for JFFS2 to find the disk. The default way uses
TODO.
- Add a new command so it's actually possible to change
- partition.
-
- Remove the assumption that JFFS can dereference a pointer
- into the disk. The current code do not work with memory holes
- or hardware with a sliding window (PCMCIA).
