[PATCH] [MTD] [NOR] Add support for the ST M29W400DB flash chip.

[Gordon Farquharson]

I submitted this patch to the list at the beginning of January in the
hope that it would be included in 2.6.25. I know that the merge window
for 2.6.25 is closed, but is it still possible to get this into
2.6.25? It is not a significant change. This chip is used in the GLAN
Tank NAS.

Thanks.

Gordon
