Artem,
Thanks for the help on upgrading out linux 2.6.33 kernel with the latest UBIFS updates. I managed to merge the UBI/UBIFS specific code from the link you gave me (I took the latest and greatest) and I have a kernel that now compiles successfully. Now we get the following error when the UBIFS file system is mounted:
UBI: attaching mtd18 to ubi0
UBI error: io_init: bad write buffer size 0 for 1 min. I/O unit
ubiattach: error!: cannot attach mtd18
error 22 (Invalid argument)
UBIFS error (pid 916): ubifs_get_sb: cannot open "ubi0:tntvar", error -19
mount: mounting ubi0:tntvar on /usr/local/tntvar failed: No such device
We are suspecting now that this may be because we need to update the ubifs tools (or create the ubifs with different cmd args) so that they are in sync with the latest kernel. If you have any ideas on this it would be great - right now I will be researching if our hypothesis is true and how to resolve it.
Thanks Dave

This means your NOR driver should be fixed and it should return
_correct_ write buffer size, not 0.

I'm guessing that you're using m25p80, which is missing this mainline
patch in the backport tree:
commit b54f47c8bcfc5f766bf13ec31bd7dd1d4726d33b
Author: Brian Norris <computersforpeace@gmail.com>
Date: Tue Jan 31 00:06:03 2012 -0800
mtd: m25p80: set writebufsize
Artem,
There was a series of 'writebufsize' fixes that may be missing from
multiple backport trees. I can help you track them down, if you'd like
the help.
Brian

Sure, go ahead, I can them put them to the backport trees.

OK, I just put up my own github backport tree, with branches for v2.6.32
through v3.3. I think your v3.4+ repos are fine. URL:
git://github.com/computersforpeace/UBIFS-backports.git
https://github.com/computersforpeace/UBIFS-backports.git
Branches:
ubifs-v2.6.32
ubifs-v2.6.33
ubifs-v2.6.34
ubifs-v2.6.35
ubifs-v2.6.36
ubifs-v2.6.37
ubifs-v2.6.38
ubifs-v2.6.39
ubifs-v3.0
ubifs-v3.1
ubifs-v3.2
ubifs-v3.3
Each branch should have some version (amended when necessary) of the
following commits. Note that docg3 wasn't merged until v3.2. Also,
spear_smi wasn't merged until v3.4 and was already fixed in the
appropriate backports, so it is omitted from this list.
