Dear MTD maintainers,

I suggest several bugfixes and workarounds against the 
snapshot of 20041226 (inserted into a vanilla 2.4.28) - see 
the attached patch.
I hope it's not a problem that my message is posted a few days
later than I would've liked - I didn't notice I had to 
subscribe to be able to post :-)

I'm using DiskOnChip devices in various sorts of Advantech 
hardware. I'm compiling my MTD drivers for the DiskOnChip 
alone - I don't want to include all the other MTD stuff 
(useless to me).

Bugs fixed / worked around:

1) if you flush the partition table and issue a BLKRRPART 
(i.e., you re-partition the diskonchip), the reported device 
size shrinks to one half of the original. If you do this again 
before a reboot, the size shrinks again (now one quarter).
Seems like the driver would re-init device size to a size denominated in 1k blocks,
rather than sectors (512B).

2) in my DiskOnChip-only setup, CONFIG_MTD_MAP_BANK_WIDTH_1 
is missing in the .config. I've added that straight to $LINUX/include/linux/map.h

3) two #includes seem to be missing in $MTD/nand/diskonchip.c

4) the Reed-Solomon library hooks are messed up in $LINUX/lib/Config.in

I hope this helps
