Subject: [PATCH 5/7] riscv: dts: add initial support for the SiFive FU540-C000 SoC
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.
