The QEMU CPU support under arch/riscv is pretty much generic and works fine for SiFive Unleashed as well. In fact, there will be quite a few RISC-V SOCs for which QEMU CPU support will work fine.
This patch renames cpu/qemu to cpu/generic to indicate the above fact. If there are SOC specific errata workarounds required in cpu/generic then those can be done at runtime in cpu/generic based on CPU vendor specific DT compatible string.
