# 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.
