nandwrite failing with IGEPv2 (OMAP 3430)

SRU justification:

impact:
 - writing to certain NAND flash configurations impossible
  (eg on IGEPv2 OMAP3430 board)
  -> thus platform flash is effectively useless
addressed how:
 - by adding support for this OneNAND geometry
patch:
 (attached)
reproducer (TEST CASE):
 1. boot Ubuntu 10.04 with board with 512MB OneNAND chips (over two banks)
 2. $ sudo nandwrite -p /dev/mtd3 uImage (or similar)
 3. should see 'Writing data to block 0 at offset 0x0' etc
 4. FAIL if 'Unknown flash (not normal NAND)'
potential for regression:
 - none, since this adds 'or' conditions and is minimal

Uploaded to maverick. Please subscribe ubuntu-sponsors for SRU upload when ready.

Please forward this patch upstream.

Daniel,

Your debdiff for lucid have to fix a couple of things.

1) debian/changelog: s/20090606-1ubuntu1/20090606-1ubuntu10.04
Usually we should use a version -1ubuntu0.1, but karmic and lucid has got the same version and we need use release number in debian/changelog.

2) debian/changelog: s/lucid/lucid-proposed

3) debian/changelog: include bug number to close bug automatically: (LP: #583280)

4) debian/control: maintainer field needs to be updated. You have to run command: update-maintainer

If you are not interested in update debdiff, I'll do this.

Hi Artur - I'm happy to test this if you can spin a package for armel. Thanks, Daniel

Accepted mtd-utils into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Daniel, please read above message and test package from lucid-proposed.

Fantastic - this works now:

# nandwrite -p /dev/mtd3 uImage
Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x40000
Writing data to block 2 at offset 0x80000
Writing data to block 3 at offset 0xc0000
Writing data to block 4 at offset 0x100000
Writing data to block 5 at offset 0x140000
Writing data to block 6 at offset 0x180000
Writing data to block 7 at offset 0x1c0000
Writing data to block 8 at offset 0x200000
Writing data to block 9 at offset 0x240000
Writing data to block 10 at offset 0x280000
Writing data to block 11 at offset 0x2c0000

This bug was fixed in the package mtd-utils - 20090606-1ubuntu0.10.04.1
