I find that many platform packages have some kind of PCD token to represent size of the PCI express region. That is the reason I think it should be standardized. As far as PCD token name and type (UINT32 vs. UINT64), I'm seeking community feedback.
Both PcdPciExpressSize and PcdPciExpressRegionLength are names used in different platform packages. -----Original Message----- From: Marvin H?user [mailto:[email protected]] Sent: Wednesday, August 02, 2017 9:57 AM To: [email protected] Cc: Felix Poludov; [email protected]; Gao, Liming Subject: RE: [PATCH] MdePkg: Add PcdPciExpressRegionLength PCD Token A bunch of platforms, such as QuarkSocPkg, already declare such a PCD named PcdPciExpressSize of type UINT64. Maybe PcdPciExpressSize|UINT64 should be 'promoted' to a MdePkg PCD and the platform-defined PCDs replaced?
