Make sure you define both TARGET and TARGET_ARCH to be 'arm'. I know
that works, as I've done this on 6.2 and -current dozens of times.
I'll take a look at -stable.
Of course, I also use the 'make buildenv' target to then build
kernels.

This is similar the atmel parts. You'd want PHYSADDR to be
0x30000000, with all the other addresses adjusted accordingly. You'd
have to see where your flash controller maps the flash memory...

There is a NetBSD port that you can crib some code from. I've looked
