What's wrong with the soc subsystem (drivers/base/soc.c).  This
provides a way to export SoC through standardised interfaces. 

It looks like the thing to use to me.

It seems to have been around only since v3.3 though, which makes it a
bit tricky to use when upgrading from running board-file based v3.2
system (Debian Wheezy) to a newer DTB based kernel, we need to select
the new DTB while running the old system.

I'd prefer to use this thing as the primary mechanism but it seems like
I'd have to implement some sort of fallback at least for one Debian
release cycle. I'm sure it is doable...

back in v3.2, lspci should still work.  Would that given you the
information you need?

I expect it will, yes.

3.14 with the new PCIe driver will also work. The patch was accepted
and considered a regression so made it into one of the -rc's.

Great! Thanks.

Ian.
