# 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.
