Subject: [PATCH 5/7] riscv: dts: add initial support for the SiFive FU540-C000 SoC
Date: Fri, 14 Dec 2018 21:21:52 -0800	[thread overview]
Message-ID: <20181215052154.24347-6-paul.walmsley@sifive.com> (raw)
In-Reply-To: <20181215052154.24347-1-paul.walmsley@sifive.com>

Add initial support for the SiFive FU540-C000 SoC.  This is a 28nm SoC
based around the SiFive U54-MC core complex and a TileLink
interconnect.

This file is expected to grow considerably as more device drivers are
added to the kernel.
