On x86 platforms, google_chromeec_early_init() is used to put the EC
into RO mode when there's a recovery request. This is to avoid training
memory multiple times when the recovery request is through an EC host
event while the EC is running RW code. Under that condition the EC will
be reset (along with the rest of the system) when the kernel verification
happens. This leads to an execessively long recovery path because of the
double reboot performing full memory training each time.
By putting this logic into the verstage program this reduces the
bootblock size on the skylake boards. Additionally, this provides the
the correct logic for all future boards since it's not tied to FSP
nor the mainboard itself. Lastly, this double memory training protection
works only for platforms which verify starting from bootblock. The
platforms which don't start verifying until after romstage need to
have their own calls (such as haswell and baytrail).
