Hi Marcus,

I believe we did not make it const at the beginning due to PCI enumeration
on Galileo.
This was early days, and things changed then.

Pretty much this was the reason.

Actually there have been plans to move it to const, at least I remember
hearing such idea
from Daniel Kalowsky, for the same exact reasons you noted, it might even
be in the git history,
somewhere. But we were too busy to follow up at that time.

I believe we even did a move that changed it to const and then ran into an
issue with a specific compiler we were to support and reverted out the
change. Might have only been in a local topic branch though.
PCI enumeration currently updates the pci_dev object in the various
config structures along with base_addr and irq_num, I propose to move
these objects from the config struct to the runtime struct.
