Subject: [PATCH v4] ARM: dts: aspeed: Adding Lenovo Hr630 BMC
Date:   Thu, 25 Apr 2019 01:39:10 +0800
Message-Id: <1556127550-234791-1-git-send-email-pengms1@lenovo.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Initial introduction of Lenovo Hr630 family equipped with
Aspeed 2500 BMC SoC. Hr630 is a x86 server development kit
with a ASPEED ast2500 BMC manufactured by Lenovo.
Specifically, This adds the Hr630 platform device tree file
used by the Hr630 BMC machines.

This also adds an entry of Hr630 device tree file in Makefile
