This is one possibility, another one is to let the platform specify how
it exports this serial, as you proposed bellow.
>>> /sys/devices/system/soc/mach/
>>> /sys/devices/system/soc/mach/name<- Name of the mach
>>> /sys/devices/system/soc/mach/foo_id

Yes it was what I thought with the foo and bar IDs exports.
