PATCH 1/1 Add support for NAND flash on cm-x255

This patch adds support for the NAND flash present on Compulab's cm-x255 boards. Since Compulab chose to discontinue cm-x255 support, I decided to submit and support this driver myself.

Note: This is the driver I wrote as part of my Compulab kernel fork project (see http://raph.people.8d.com/armcore_kernel.php). It is not based on the driver Mike posted to the list.

Applies to 2.6.18-rc2.
