When the board name is Linuxstamp, and the board directory name is
linuxstamp, then the board config file name and make target name
should be linuxstamp, too.

Argh... AT91 "style" again. we should really clean up all this mess
one day...

This seems to be wrong. Should this not be something like
MACH_TYPE_STAMP9G20 instead?

NAK. Please fix your Linux drivers instead. See

see above for choice of file name.

This is most certainly NOT a AT91SAM9260EK board, right?

Don't undef what is not defined anyway.

Ditto.

Is there any specific reason for disabling lots of pretty useful
commands? Are you so tight on flash memory or RAM?

AT91SAM9G20EK ?
