This is a simple patch which allows payloads to be placed in memory in the range of 0xf0000-0x100000, where the Coreboot tables live in v2. As long as the payload doesn't need the tables, it seems harmless, so why not just print a warning?
It will definitely break your interrupt routing ... While I agree this is OK for testing, we have to find a better solution for this.
Yes.
As soon as we decide how we want to pass information to legacybios, it should be clear what the better solution is.
One solution is a libpayload-based loader that copies the information
and
passes the relevant parts to legacybios. Until legacybios uses any of
that
information, though, it might as well be copied over.
It'll be fine for testing and doesn't really break anything that did work before...
