Message-ID: <DB7PR08MB3097A3D8B247A7D6A12AE15C84B99@DB7PR08MB3097.eurprd08.prod.outlook.com> (raw)

Hi Pranav,
PcdAcpiExposedTableVersions = 2 is needed to meet the BBR requirement, see Arm Base Boot Requirements 1.0, Section 8.3.1.1 RSDP
"Within the RSDP, the RsdtAddress field must be null (zero) and the XsdtAddresss must be a valid, non-null, 64-bit value"
So, you might want to update the commit message to reflect this.
Otherwise, these changes look fine to me.
Reviewed-by: Sami Mujawar <sami.mujawar@arm.com>
Regards,
Sami Mujawar

Subject: [edk2-devel] [edk2-platforms][PATCH V1 1/1] Platform/ARM/SgiPkg: Update ACPI Table revision
Fix the ACPI DSDT/SSDT table version numbers. As per ACPI 6.3
specification, the DSDT/SSDT table should use version 2 instead of 1. In
addition to this, update 'PcdAcpiExposedTableVersions' to avoid building
RSDT table into ACPI firmware volume because the platforms supported
under SgiPkg are 64-bit systems only and require only the XSDT table.
