      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_*"
