[coreboot] X86 considered harmfull vs Coreboot

[NTPT]

Hi all 

I found a paper 
Intel x86 considered harmful
Joanna Rutkowska

http://blog.invisiblethings.org/papers/2015/x86_harmful.pdf

describing  things that are belived are security shorcommings of x86 architecture. Many of them are bios / mb  and boot process related. 

I am just awandering how coreboot as a  "opensource bios"  deal with this... 

Any information ?  I would glad to hear Yours opinion . Thanx
