From 792ebb6374f2b92e2c4b84f5b8d151a129ed81cc Mon Sep 17 00:00:00 2001 From: Pierre Gondois Date: Wed, 7 Apr 2021 15:43:39 +0100 Subject: DynamicTablesPkg: Fix generated _HID value for SBSA SSDT tables describing an SBSA compatible serial port receive an '_HID' value of 'ARMH0011'. This value represents a PL011 serial port. This patch: - Generates an 'ARMHB000' instead - References the 'ACPI for Arm Components 1.0 - 2020' document specifying the '_HID' values to use.
