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.
