Subject: [PATCH] [PATCH v1] ARM: dts: aspeed: Adding Lenovo Hr855xg2 BMC
Date: Tue, 25 Jun 2019 14:38:16 +0800	[thread overview]
Message-ID: <1561444696-446373-1-git-send-email-pengms1@lenovo.com> (raw)

Initial introduction of Lenovo Hr855xg2 family equipped with
Aspeed 2500 BMC SoC. Hr855xg2 is a x86 server development kit
with a ASPEED ast2500 BMC manufactured by Lenovo.
Specifically, This adds the Hr855xg2 platform device tree file
used by the Hr855xg2 BMC machines.

This also adds an entry of Hr855xg2 device tree file in Makefile
