[PATCH v2 0/4] PCI: of: Improvements to handle 64-bit attribute for non-prefetchable ranges

[Punit Agrawal]

Hi,

Here's an updated version of changes to improve handling of the 64-bit
attribute on non-prefetchable host bridge ranges. Previous version can
be found at [0].

The series addresses Rob and Bjorn's comments on the previous version
and updates the checks for 32-bit non-prefetchable window size to only
apply to non 64-bit ranges.

Thanks,
Punit

Changes:
v2:
* Check ranges PCI / bus addresses rather than CPU addresses
* (new) Restrict 32-bit size warnings on ranges that don't have the 64-bit attribute set
* Refactor the 32-bit size warning to the range parsing loop. This
  change also prints the warnings right after the window mappings are
  logged.
