From d12530cb838c4fa2d503d27c9ea19e8ffb515725 Mon Sep 17 00:00:00 2001 From: Werner Zeh Date: Fri, 14 Dec 2018 13:09:12 +0100 Subject: intelblocks/systemagent: Add ACPI table generation hook In preparation of generating DMAR tables, provide the hook in SoC scope for the systemagent to write ACPI tables. The complete functionality is SoC-specific. Therefore the entry hook is defined as a weak function which can be overridden by SoC code. If the SoC does not have support for generating DMAR tables this hook will do no harm.
