# This makefile is constructed from a machine description:

# 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.
