In platform which support ACPI 2.0 only, the base address of ACPI region is not page aligned. This unalinged base address leads to failure at BuildMemoryAllocationHob when parsing ACPI node in FdtParserLib, before building gUniversalPayloadAcpiTableGuid GUID HOB. Align base address of ACPI region down to EFI_PAGE_SIZE to make sure base address always aligned. Signed-off-by: Ajan Zhong <ajan.zhong@newfw.com> |
