Further tweaks on the horizon (for v2, or on top), highlighted by Drew
Jones:
- explain -kernel/-initrd/-append (after testing it, of course! I'm
unsure if fw_cfg kernel boot actually works with RiscVVirt!)
- point out that -bios (OpenSBI) makes no difference under KVM, as KVM
services those SBI ecalls
- explain "acpi=off" (in the context, not in the added text): Linux
support (i.e. the ACPI *consumer* side) is still under development /
work in progress.

This looks fine to me as far as an edit, but I didn't validate the commands.

Do we need to duplicate these OpenSBI build instructions in EDK2? IMO,
we should just document how to use -bios to use custom OpenSBI image.
The build instructions for other software repos can change at any
time.

Hi Laszlo,
Yes, I think providing the URL is a good idea.

BTW, I disagree with your larger message (as I perceive it).
While it's true that build instructions may change at any time, that's
just a generic statement about any software and any documentation in
existence. All documentation goes stale at some point.
And in this particular case, I needed to fish out the build commands,
and the resultant "fw_dynamic.bin" filename, from the QEMU tree, not the
OpenSBI tree. I'm not aware of any documentation that makes a dedicated
statement about building OpenSBI *for* running edk2.
The OpenSBI root "README.md" @ b20bd479eff1 only says "For example, to
compile the platform library and the firmware examples for the QEMU
RISC-V *virt* machine, *<platform_subdir>* should be *generic*". It does
not mention the build output pathname
"build/platform/generic/firmware/fw_dynamic.bin".

Agreed. But my point is, this documentation which provides build
instructions of opensbi doesn't belong to edk2 but opensbi. If something
is missing in the opensbi build instructions like you mentioned, it
should be submitted as a patch to opensbi repo rather edk2, right?

I don't know.
If two projects are used in conjunction, which project's documentation
should cover the combined use?

Okay, fair enough. Let's add it. It appears to be very useful for any
one new to RISC-V+edk2 and OpenSBI. Do you want to update the -kernel
option also in v2 or will it be separate patch?

I think I'd like -kernel etc to be an incremental (= separate) patch,
because first I need to test it.
