You'll have to find out which ARM core is closest to yours and grep the .cfg
files for examples.

I briefly looked at the board specs.  Looks like the flash is on CS6.
You'll have to figure out what mww commands are needed to strap the
registers enough to enable that chip select.

That is about all that came to mind so far.  Hope you get it going!
