Description

I followed the build instruction I found online and was able to build a coreboot with a BBL+vmlinux payload, a vmlinux kernel and a coreinfo payload.

When I run either one under qemu-system-riscv64 I get a expection fault:
Before I go digging into the code, I wanted to see if this was a known issue? Or if I am doing something wrong? I have used this qemu to boot another riscv image (bbl)

CMDLINE: qemu-system-riscv64 -M virt -m 1024M -nographic -kernel build/coreboot.elf

Output:
qemu-system-riscv64: warning: No -bios option specified. Not loading a firmware.
qemu-system-riscv64: warning: This default will change in a future QEMU release. Please use the -bios option to avoid breakages when this happens.
qemu-system-riscv64: warning: See QEMU's deprecation documentation for details.
