   5 # This makefile is constructed from a machine description:
   6 #       config machineid
   7 # Most changes should be made in the machine description
   8 #       /sys/arch/<arch>/conf/``machineid''
   9 # after which you should do
  10 #       config machineid
  11 # Machine generic makefile changes should be made in
  12 #       /sys/arch/arm/conf/Makefile.arm
  13 # after which config should be rerun for all machines of that type.
  14 #
  15 # To specify debugging, add the config line: makeoptions DEBUG="-g"
  16 # A better way is to specify -g only for a few files.
  17 #
  18 #       makeoptions DEBUGLIST="uvm* trap if_*"
