[Bug 1904802] Re: please provide firmware file for riscv64

[Heinrich Schuchardt]

The QEMU source comes with bundled OpenSBI binaries ./pc-bios/opensbi-
riscv*-generic-fw_dynamic.*

docs/system/riscv/virt.rst describes booting in S-mode without the -bios
option only using -kernel. To my understanding the bundled OpenSBI
binaries are used.

Bug description:
  please provide firmware file for riscv64

  
  I'm not sure which package should ship it, or what it should look like, but i want something like this:

  qemu-system-riscv64 -machine virt -m 2048 -smp 4 -kernel
  /usr/lib/riscv64-linux-gnu/opensbi/generic/fw_jump.elf -device
  loader,file=/usr/lib/u-boot/qemu-
  riscv64_smode/uboot.elf,addr=0x80200000 -device virtio-blk-
  device,drive=vda -drive file=livecd.ubuntu-cpc.img,id=vda -device
  virtio-net-device,netdev=eth0 -netdev user,id=eth0

  
  such that on riscv64 opensbi loader is available as firmware, with qemu smode uboot.elf.

  I don't know how to write the appropriate qmeu/firmware/*.json for it.
