You have CONFIG_MTD_PHYSMAP turned off in your kernel configuration.

No, it's a template kernel config file that has everything enabled
that you would normally need.  Try typing this:

	make ARCH=arm ep93xx_defconfig

On top of that, you probably also need the (uncommented) head.S hunk
from this patch (as my TS7250 doesn't pass the right machine ID, so
yours probably doesn't either):

	http://svn.wantstofly.org/ep93xx/local.diff

Let me know if that works for you.


cheers,
