Pi-Hsun, is this patchset still an RFC or you really want to see this
merged ASAP? If I am not mistaken there is still some work in progress
trying to push all the SCP stuff?

Lee, personally I have some concerns. Looks like the cros_* family is
increasing quickly lately (cros_ec, cros_pd, cros_scp, cros_ish,
cros_fp ...) and I am wondering if we are really doing well all this.
To be honest, I'd like to take a deeper look before merge this, btw I
thought there was no hurry because of the RFC and I guess there are
still some scp things that are missing. I might be wrong, and if
that's not the case I can take a look deeper and the end of the week.

Best regards,
Enric
