# config machineid

# Most changes should be made in the machine description

# /sys/riscv/conf/``machineid''

# after which you should do
|
|
# config machineid
|

# Generic makefile changes should be made in
|
|
# /sys/conf/Makefile.riscv
|
|
# after which config should be rerun for all machines.

|
|

# Which version of config(8) is required.
