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

[Gordon Farquharson]

Please could somebody acknowledge this patch. I have sent it to
linux-mtd several times and received no response [1]. It was
originally posted to linux-mtd on 2008-01-08 in the hope that it would
be included in 2.6.25.

Thanks.
