Ian Lepore a297028904 Remove all traces of support for ARM chips prior to the arm9 series. We
never actually ran on these chips (other than using SA1 support in an
emulator to do the early porting to FreeBSD long long ago).  The clutter
and complexity of some of this code keeps getting in the way of other
maintenance, so it's time to go.

# Makefile for FreeBSD

# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/arm/conf/``machineid''
# after which you should do
# config machineid
# Generic makefile changes should be made in
# /sys/conf/Makefile.arm
# after which config should be rerun for all machines.

# Which version of config(8) is required.
