Fwd: sharpsl nand driver still broken in current git

[Steven Newbury]

I somehow managed to misread the git changelog and get the wrong mailing list
first try so exchange ARM merge for MTD merge below.

rmk wasn't impressed!

I should add that the machine is a Sharp Zaurus SL-C3100 (Borzoi) and the
normal boot on ealier kernels appears as below:

Sharp SL series flash device: 800000 at 0
Using static partision definition
Creating 1 MTD partitions on "sharpsl-flash":
0x00140000-0x007f0000 : "Boot PROM Filesystem"
NAND device: Manufacturer ID: 0xec, Chip ID: 0xf1 (Samsung NAND 128MiB 3,3V 8-b
Scanning device for bad blocks
Creating 3 MTD partitions on "sharpsl-nand":
0x00000000-0x00700000 : "System Area"
0x00700000-0x08000000 : "Root Filesystem"
0x08000000-0x08000000 : "Home Filesystem"
mtd: partition "Home Filesystem" is out of reach -- disabled

I converted the driver blindly after I changed the core code. Richard
can you please look into that ?

The conversion was at fault and a patch to fix it will follow this mail.

I'm loathed to create an mtd git tree containing it as last time I spent
time doing this, the pull request was totally ignored and someone else
ended up duplicating the work.
