Agreed. When looking at the code, I wasn't sure why PCI mappings were
needed so early. Surely, the minimal mappings to get an UART are quite
useful to have very early, but why PCI?

I think it was because that PCI was initialised early and requires a
large mapping space. It is very likely to be legacy kernel stuff that
people have kept copying through.

No, as Rob pointed out, we might not need them early, but we definitely
want a fixed address for the PIO window, which ioremap does not
provide.
