# Most changes should be made in the machine description

# /sys/arch/<arch>/conf/``machineid''
|
|
# after which you should do

# config machineid
|
|
# Machine generic makefile changes should be made in

# /sys/arch/arm/conf/Makefile.arm

# after which config should be rerun for all machines of that type.

# DEBUG is set to -g if debugging.
