+Abstract:
+
+  This is an implementation of the ACPI platform driver.  Requirements for

+  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.
