# Expose the tPad touchscreen device via an Avalon "generic" device.  Observe
# that this is a portion of DRAM, so some care may be required in how memory
# is exposed to FreeBSD to avoid use of that DRAM for both the touch screen
# and FreeBSD use.
#
# Two separate devices are used here because alignment/width requirements for
# I/O differ: the frame buffer accepts 16-bit I/O, and the touch input device
# requires 32-bit I/O.
