The one that should run everywhere is Google's depthcharge, and that
isn't hooked up to the build system like SeaBIOS is (and even
depthcharge isn't available for emulation/qemu-riscv). So you're
correct, there is no single payload for every board.

Since we select default payloads in our Kconfig rules (seabios for
x86), I guess we should start doing the same for other architectures.
I don't think that belongs in your test script - things might change
in the future, and that shouldn't require additional effort on your
We'll work on that, and will tell you once there's a plan and/or implementation.

There are distributions, sort of.
Google ships coreboot as part of Chrome OS (which requires a huge
build system even to build just coreboot).
Then there's libreboot (www.libreboot.org), which ships their
coreboot-variant (without blobs and with as few patches against
coreboot as possible) with GRUB2 as payload for a small selection of
boards that they can support.
There are also some other vendors, but they're less visible.
If you want to support coreboot distributions (that ship binaries),
libreboot is currently your best bet.

Oh, I loved it, still do! At some point we should replace the question
mark with an exclamation mark, though :-)

Thanks, will do. Let's start immediately :-)
Since you mentioned 'once we reach 100% (without payloads)' earlier:
the issue of the remaining 7 non-reproducible board should be fixed
since today, in response to your report. I'd appreciate if you could
do another run to verify this.
