Oh wow, an SPI NOR flash.  In my opinion, this is a rare constellation,
so you will probably need to debug MTD in Linux.

Ok, so the problem is really that the MTD layer does not know how to
talk to your spi flash.  I will not be of much help here, I'm afraid, so
I'll advise to find a mailing list closer to the problem...

Well if one reads lots and lots of messages, it is basically important that
everybody uses an e-mail style allowing efficient processing.  There is
a good FAQ on this:
