Cover letter [PATCH 00/16] PCI generic configuration space accessors
This series adds common accessor functions for PCI configuration space accesses. This supports most PCI hosts with memory mapped configuration space like ECAM or hosts with memory mapped address/data registers. ECAM is not generically supported by this series, but could be added on top of this. While some hosts have standard address decoding which could be common as well, the various checks on bus numbers and device numbers are quite varied. It is unclear how much of that is really necessary or could be common.
The first 4 patches are preparatory cleanup. Patch 5 introduces the common accessors. The remaining patches convert several PCI host controllers. This is in no way a complete list of host controllers. The conversion of more hosts should be possible. The Designware controller in particular should be able to be converted, but its config space accessors are a mess of override-able functions that I've not gotten my head around.
This series is available here [1].
