sorry as I explain before if you have exclusive option you need to create
kconfig options which are board specific to manage them
we work to reduce the number of defconfig in the mainline
and it's not PortuxG20 and Stamp9g20 specific but to have only one defconfig
for all 9g20 at a first step and late for all sam9

two bards with the same machine id NACK as we can not compile them in the same
kernel and this a target we all work on to allow
if you want to tuse the same machine id as I did for other boards you must use
system_rev or any detection to identify tehm
