I do carry several experiment patches in Fedora/RISCV, which I didn't
yet sent for a review.
Basically that allows me to boot a single Fedora/RISCV disk image on
QEMU virt machine
and SiFive Unleashed.

See: http://fedora.riscv.rocks:3000/rpms/uboot-tools/src/branch/master-riscv64/uboot-tools.spec#L36

Note some of the patches were merged in rc5.

You would want the following two patches:
http://fedora.riscv.rocks:3000/rpms/uboot-tools/src/branch/master-riscv64/riscv64-set-fdt_addr.patch
http://fedora.riscv.rocks:3000/rpms/uboot-tools/src/branch/master-riscv64/riscv-bootargs-preboot.patch

If you could review them I could send them out.
