Subject: [TEST PATCH 31/30][EDK2] edk2-platform: juno: Update ACPI CoreSight Bindings
Date:   Wed, 22 May 2019 11:35:04 +0100
Message-Id: <1558521304-27469-32-git-send-email-suzuki.poulose@arm.com>
In-Reply-To: <1558521304-27469-1-git-send-email-suzuki.poulose@arm.com>
References: <1558521304-27469-1-git-send-email-suzuki.poulose@arm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

ACPI bindings for CoreSight components on the Juno-r0 board.
Please note that the bindings apply only for the juno-r0.
The layout on r1 and r2 are slightly different and will need
dynamic ACPI table support to be able to use a single UEFI
image.
