My next step is to make copy_and_run cbfs aware. That would push the 
coreboot_ram part of both stages into cbfs already, significantly 
decreasing the bootblock size.

It's a low hanging fruit given that copy_and_run is a single code path 
now, and that at this time of the boot process, RAM is available.

After that, I wanted to take a look at the location calculation stuff 
that determines where normal is linked to. That would fix normal and I 
think it can be automated in a way that works for both cbfs and 
"old-style". That would mean less numbers to tweak, too.

Unless you really want to put the remaining fallback/normal code into 
cbfs, in which case that work would be useless. I really like the idea 
of using %cs, if it's known to be stable.
