......................................................................

Patch Set 4:

I agree to the change but I think somebody at Intel should really
investigate what the processor supports and what MSRs exist. It looks
like the configure_dca_cap() function is plain copy-pasta, I traced
it back to Sandybridge. But it was already there implemented wrong
anyway if you compare it to the BWG. I also have doubts if there ever
was any Intel processor with DCA supported by coreboot.
