Hello Jérémy Compostella, Patrick Rudolph, build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/79738?usp=email

to look at the new patch set (#4).

Change subject: smmstorev2: Load the communication buffer at SMM setup
......................................................................

smmstorev2: Load the communication buffer at SMM setup

This removes the runtime SMI call to set up the communication buffer
for SMMSTORE in favor of setting this buffer up during the installation
of the smihandler.

The reason is that it's less code in the handler and a time costly SMI
is also avoided in ramstage.
