Fujitsu MBM29SL800TE flash support

Hi,

This is my first post to the list.  First, I would like to thank
everyone for their work on OpenOCD, it is a great tool to work with.  I
have been using it to debug code on hardware for the Rockbox project
(www.rockbox.org).

The target that I primarily work with has a Spansion/Fujitsu NOR flash
(MBM29SL800TE).  I attached a patch that adds support for this flash.  I
hope it can be included in the main repository.  If there is something
that needs to be changed with the patch before inclusion please let me
know.
