[coreboot] Placing coreboot in system memory

[Julian Stecklina]

Hi!

I have a bit of a newbie question. We're using Coreboot in VMs in our custom
virtualization stack for x86. We are mapping the whole Coreboot image into guest
physical memory so its end coincides with 4G. This makes Coreboot's reset vector
entry point line up with where the hardware wants to start executing.

This works, but I wonder whether this is the intended way to use Coreboot or
whether there is some more elaborate way to do it. Does all of Coreboot have to
be mapped at the end of 4G? Or is there any documentation on this?

Thanks for any pointers,
Julian
