To: devel; +Cc: Ard Biesheuvel, Leif Lindholm
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.

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.

Regards,
Sami Mujawar

Adding Ard's new email
PcdAcpiExposedTableVersions already defaults (in MdeModulePkg.dec) to 0x20 for AARCH64. This was done as part of a commit a while go to fix this for all Aarch64 platforms: https://github.com/tianocore/edk2/commit/40b9ca6beb8c5cd11e9fb30ebc447c7889157eff.
