[PATCH 0/4] arch: riscv: add board and SoC DT file support

[Yash Shah <yash.shah@sifive.com>]

Start board support by adding initial support for the SiFive FU740 SoC
and the first development board that uses it, the SiFive HiFive
Unmatched A00.

Boot-tested on Linux 5.10-rc4 on a HiFive Unmatched A00 board using the
U-boot and OpenSBI.

This patch series is dependent on Zong's Patchset[0]. The patchset also
adds two new nodes in dtsi file. The binding documentation patch
for these nodes are already posted on the mailing list[1][2].
