From 3900a63e3a1b9ba9a4105bedead7b986188cec2c Mon Sep 17 00:00:00 2001 From: Ray Ni Date: Wed, 17 Jun 2020 16:34:29 +0800 Subject: [PATCH] UefiPayloadPkg/Pci: Use the PCIE Base Addr stored in AcpiBoardInfo HOB Today's UefiPayloadPkg always uses 0xE0000000 as the PCIE base address and ignores the value set in AcpiBoardInfo HOB created by the boot loader. This makes the payload binary cannot work in environment where the PCIE base address set by boot loader doesn't equal to 0xE0000000. The patch enhances UefiPayloadPkg so that the PCIE base address set by boot loader in the AcpiBoardInfo HOB is used.
