The ARM Versatile boards are two variants of ARM926EJ-S evaluation boards
with various pluggable interface boards, in essence the Versatile PB version
is a superset of the Versatile AB version.

evaluation board specifically for the ARM926EJ-S. It can be connected
to an IB1 interface board for a touchscreen-type use case or an IB2
for a candybar phone-type use case. See ARM DUI 0225D.
