Do we want to take fixed resources into account in the allocator?
I would think so.
I would too, but v2 didn't and did pretty well. I'm interested to see an idea for the resource allocation algorithm that allocates from largest to smallest resource, except when it's skipping fixed resources.
I think it's doable, but nothing like what we have.
That surprises me. I thought it does, which is how/why you can get rid of DEVICE_MEM_HIGH. Otherwise you would clobber the ROM and the APIC.
And that brings up where to reserve the ROM space. In the southbridge subtractive device code I guess?
