Not exactly, no, the documentation really should say. You can
experiment---are there some status registers whose values
you would recognize? Could print out several registers from
each of the mappings and work out which is which. Sometimes
the device will map its internal registers to both a memory
BAR and an I/O BAR, so the first two in your listing could
well be windows onto the same locations.

I'm not sure I understand the "paging"---certainly PCI itself
is linearly addressed, so you just ask for location n. I suppose
some devices might have a scheme for writing an address first,
then reading the corresponding value (thus saving address space),
but there's little need for this sort of thing in a new design.
