+ Called for every ACPI table found in the BIOS flash.
+ Returns whether a table is active or not. Inactive tables
+ are not published in the ACPI table list. This hook can be
+ used to implement optional SSDT tables or enabling/disabling
+ specific functionality (e.g. SPCR table) based on a setup
+ switch or platform preference. In case of optional SSDT tables,
+ the platform flash will include all the SSDT tables but will
+ return EFI_SUCCESS only for those tables that need to be
+ published.
+ This hook can also be used to update the table data. The header
+ is updated by the common code. For example, if a platform wants
+ to use an SSDT table to export some platform settings to the
+ ACPI code, it needs to update the data inside that SSDT based
+ on platform preferences in this hook.
