I do not think the term "NOR" flash is correct.
"NOR" refers to the technology used in the memory cell,
and both "SPI Flash" and "Dataflash" are "NOR" flashes.
A better term is "parallel flash".

Atmel obsoleted all "parallel" flash during 2010, so
don't expect any boards to contain "parallel" flash
to come out in the future.

Looks like boards.cfg does not even contain most at91 boards
for some reason, so MAKEALL does not even try to build them
Think that should be fixed.
