DB1x00 FLASH and Kernel 2.6.8.1

DB1x00 FLASH and Kernel 2.6.8.1

[Charles Eidsness]

Hi All,

I had to make a minor change to the db1x00 flash's memory map definition 
file in version 2.6.8.1 of the kernel in order to get flash support to 
compile. See attached patch if interested.

Cheers,
Charles

I fixed this recently and pushed the patch in linux-mips and the mtd tree.
