In the future, please thread the 0/N to the patch series, thanks.

So the root problem is that you are able to share a good amount of code
between many (but lets just go with a10a and a10b for now) boards and
share a common config file.  When building for a10a in boards.cfg you
do:
a10a ... allwinner_common:PERIPHERALX=A10A,PERIPHERALY=A10A
a10b ... allwinner_common:PERIPHERALX=A10B,PERIPHERALY=A10B

to handle the differences between a10a and a10b.  So, what are you
wanting to save the fact that we built for a10a or a10b for?  Is this
later passed along in the environment for run-time detection?  Is there
no other way to do run-time detection?
