    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.
