Hi Joonathan,

Thank you for the information. I don't have RISC-V hardware available
right now. As you told QEMU won't work , it seems I may not able to do
any development[ right ?]. BTW I have Beagle Bone Black I can port
coreboot on that one if it's not available.  I was lurking on IRC and
came to know that there are few patches on Beagle bone available. I
have checked it out beagle bone has support for coreboot but not sure
about beagle bone black. I will try it on BBB and let you know about
that :)

Thanks,
Punit Vara
