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).
