[edk2-devel] [edk2-platforms: PATCH 07/14] Marvell/Armada7k8k: Implement PciHostBridgeLib
Add an implementation of the PciHostBridgeLib glue library that describes the PCIe RC on this SoC so that the generic PCI host bridge driver can attach to it. This includes a constructor which performs the SoC specific init and training sequences. This patch is based on work of Ard Biesheuvel and Jing Hua / Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Marcin Wojtas --- Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLib.inf | 52 +++ Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLibConstructor.h | 95 ++ Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLib.c | 244 +++ Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLibConstructor.c | 330 4 files changed, 721 insertions(+) create mode 100644 Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLib.inf create mode 100644 Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLibConstructor.h create mode 100644 Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLib.c create mode 100644 Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLibConstructor.c diff --git a/Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLib.inf b/Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLib.inf new file mode 100644 index 000..e46f71d --- /dev/null +++ b/Silicon/Marvell/Armada7k8k/Library/Armada7k8kPciHostBridgeLib/PciHostBridgeLib.inf @@ -0,0 +1,52 @@ +## @file +# PCI Host Bridge Library instance for Marvell Armada 7k/8k SOC +# +# Copyright (c) 2017, Linaro Ltd.
