Driver changes mostly get reviewed by subsystem maintainers rather than architecture maintainers.

At some point, this file will get turned into yaml, at which point substitution like this will need expanding. It is better to do that now. Andrew

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].
