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].

Aside from that question about the i2c bug these look good to me. I don't see any Ack/Review on the DT side of things, though. If you want to take them through a DT tree that's fine for me, I'll leave them in my inbox for now and if nobody says anything I'll look a bit more and take them for 5.12.
