Subject: [PATCH v2 12/22] ACPICA: ACPI 6.4: add SDEV secure access components
Date: Tue,  6 Apr 2021 14:30:18 -0700	[thread overview]
Message-ID: <20210406213028.718796-13-erik.kaneda@intel.com> (raw)
In-Reply-To: <20210406213028.718796-1-erik.kaneda@intel.com>

ACPICA commit 44ca5f4f9be24bf64524cdb1de46322509319056

This entails adding an optional subtable indicating secure access
components as well as two different types of secure access components
(ID-based or Memory). For definitons and uses, consult the ACPI
specification.
