Not if the stage definition is in main. I realized some time ago that
arch/x86/stage1.c is misnamed (my fault) -- since it alls all the
stages.

It's really what we used to call hardwaremain, I wonder if we should
just call it coreboot main or something.

Marc, is it really possible to shadow bios if it is up in high memory?
Or do we have to shadow fxxxx addresses?

If we have to shadow fxxxx addresses, then we need to do something like this:

assembly
First C code calls stage1
disable_car
shadow boot block to fxxxx
jump to entry point in fxxxx
stage 2 payload, run it
other code
payload
jump to payload

or not?
