Create a new Styx platform driver StyxSataPlatformDxe which contains the existing platform specific SATA initialization code (including the AHCI register descriptions in SataRegisters.h), but uses the new non-discoverable device protocol to register the platform AHCI devices. This has two advantages: - we can use generic drivers for the non-discoverable PCI I/O emulation, and for the AHCI support built on top of it, - we can register both SATA devices, allowing us to use all 14 ports on Overdrive B1 Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> --- Platforms/AMD/Styx/Drivers/StyxSataPlatformDxe/InitController.c | 188 ++++++++++++++++++++ Platforms/AMD/Styx/Drivers/StyxSataPlatformDxe/SataRegisters.h | 180 +++++++++++++++++++ Platforms/AMD/Styx/Drivers/StyxSataPlatformDxe/StyxSataPlatformDxe.inf | 61 +++++++ 3 files changed, 429 insertions(+)
