IntelSiliconPkg IntelVTdDxe: use gEfiAcpi10TableGuid for ACPI 1.0

[edk2] [PATCH] IntelSiliconPkg IntelVTdDxe: use gEfiAcpi10TableGuid for ACPI 1.0

Posted by Star Zeng 6 years, 5 months ago

According to definition (Acpi.h and MdePkg.dec),
gEfiAcpiTableGuid = gEfiAcpi20TableGuid, and the code is trying
to parse ACPI 2.0 first and then ACPI 1.0, but it uses
gEfiAcpiTableGuid wrongly for ACPI 1.0, this patch is to fix it.
