This patch adds NAND driver to recent git. Tested on DM6446 DVEVM.
It is mainly based on Sander Huijsen <[EMAIL PROTECTED]> work

I'm a little disappointed that you didn't pick one of the replacement
routines, but
I can understand wanting to maintain compatibility with software ecc. So
with the aim
of speeding up the code without changing formats, here's a new routine
to kick the tire.
(nand_davinci_gen_true_ecc_compatible,nand_davinci_compare_ecc_compatible)
Sorry, I didn't want to disappoint you. And, no, I didn't want
anything special like maintain compatibility.
I just tried to understand which parts of your user space nandtest.c
you want me to put into the driver and seems that due to missing ECC
knowledge I failed. Sorry.
It would help if you kindly would send exactly and only the code part
you like to see in the driver. Then I can simply copy & paste it and
hopefully I will get this right ;) Best format would be a patch on top
of my v3 patch or a complete file davinci_nand.c with what you want to
have in it, based on my v3 as well. I then will re-package it to v4
version of my patch.
Btw: Maybe this question is stupid again, but your code mentions "256
or 512 bytes/ecc". Whats about 2048byte pages? We had a request on the
list whether the driver will work with 2k page NANDs as well.
Many thanks for your help
Dirk
