0013 The ARM Versatile boards are two variants of ARM926EJ-S evaluation boards
0014 with various pluggable interface boards, in essence the Versatile PB version
0015 is a superset of the Versatile AB version.

0023 evaluation board specifically for the ARM926EJ-S. It can be connected
0024 to an IB1 interface board for a touchscreen-type use case or an IB2
0025 for a candybar phone-type use case. See ARM DUI 0225D.
