Do you have vmlinux embedded in bbl ?

With separate bbl and vmlinux, and the following qemu command line 
(with qemu 3.0)

qemu-system-riscv64 -M virt -m 512M -no-reboot \
	-bios bbl -kernel vmlinux \
	-netdev user,id=net0 -device virtio-net-device,netdev=net0 \
	-device virtio-blk-device,drive=d0 \
	-drive file=rootfs.ext2,if=none,id=d0,format=raw \
	-append 'root=/dev/vda rw console=ttyS0,115200' \
	-nographic -monitor none

all I get is

rom: requested regions overlap (rom mrom.reset. free=0x000000000001cbe8, addr=0x0000000000001000)

However, the she system boots fine with the same qemu command line if I use qemu
built from https://github.com/riscv/riscv-qemu.git, branch qemu-for-upstream.

Excellent - once this series hits mainline, I'll add riscv to my
boot tests.

Thanks,
Guenter
