as it doesn't seem to be used by some architectures. Does it mean it
is not needed unless you have some BIOS setting up resources for you
and in that case you need to go and claim the resource?

Many architectures don't use pci_claim_resource() yet.  I'm trying to
unify this so all architectures do use it, but it's taking me a long
time to get this done.
