   8 # This makefile is constructed from a machine description:
   9 #       config machineid
  10 # Most changes should be made in the machine description
  11 #       /sys/arm/conf/``machineid''
  12 # after which you should do
  13 #        config machineid
  14 # Generic makefile changes should be made in
  15 #       /sys/conf/Makefile.arm
  16 # after which config should be rerun for all machines.
  17 #
  18
  19 # Which version of config(8) is required.
