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].
