Closed by commit rG896f556205c8: Add the fixed memory type to the pci ecam driver (authored by andrew). · Explain Why

This revision was automatically updated to reflect the committed changes.

andrew added a commit: rG896f556205c8: Add the fixed memory type to the pci ecam driver.

This patch apparently has not been MFC'ed to 13-stable, preventing the Windows 2023 Dev Kit from booting 13.2-RC6 (in conjunction with D37765 and hw.pac.enable=0). Could this one be MFC'ed?
