Here's another stab at this writeup. I'd appreciate any comments!
Changes from v1 to v2: - Consumer/Producer is defined for Extended Address Space descriptors; should be ignored for QWord/DWord/Word Address Space descriptors - New arches may use Extended Address Space descriptors in PNP0A03 for bridge registers, including ECAM (if the arch adds support for this) - Add more details about MCFG and _CBA (Lv's suggestion) - Incorporate Rafael's suggestions
