Or, actually, it was more simple and I'd just forgotten the terminating
0 on the keymap table.


is my updated patch against Mark's initial patch.

Main features are:

* A more fully mapped omap-keypad table - all the letters and the
  numbers on the keypad should work now (any idea how to test this? I
  couldn't see a /dev file to easily ready to be sure it was outputting
  the right things.)
* NAND flash driver - the mtd partitions table is still in flux, but I
  have / mounted off a jffs2 partition on my E3 now. Note that doing
  this seems to make PBL unhappy when it does its scan through flash;
  it'll stop and just sit there, but pbltool still works fine.
* A start at LCD support. I know Mark is working on this, but LCD stuff
  touches latch2 which is also used by the NAND, so I started on this.
  I'm not getting anything though; possibly the clock rates are the

I'd like to see the LCD stuff finished; Mark, any input you have or work
