This may be useful to work around potential PCIe issues. Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Ard Biesheuvel --- v2: Make the speed limit per-slot instead of per-RC. That does make this implementation more specific to DeveloperBox than it was before, but given the special knowledge about the on-board ASM1184e switch and the need for enabling spread-spectrum on the ASM1061, we're already past the point where PlatformDxe is a generic SynQuacer driver, and we may need to move it into Platform/Socionext (and clone it for each platform) in the future.
