Hello,

AFAICS the qemu patch that adds support for handling separate bbl
and kernel images, i.e.

https://github.com/riscv/riscv-qemu/commit/6338416ecf4717197c635b5abf9c17465d2d0da0

hasn't yet made it into upstream qemu, so using the "-bios"
option for bbl generally doesn't work with (upstream) qemu 3.0.

Regards,
Karsten
