Yay!

I feared as much, so thats why I asked ;)

This is a problem that will turn up in the future even more, so I
propose to solve it correctly now. It will not be long before we want
to have our own configuration for our MCV module and this will certainly
be sold by DENX. I think we need an infrastructure to allow for boards
sold by arbitrary manufacturers all using the Altera chip.

The situation as such is not uncommon, so maybe you can follow examples
from different CPUs? I.e. how is the imx6 handled on the different base
boards?

Cheers
