# 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.
