From 733c28fa4228b1ce000d39e2807ebc3224302a7a Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Mon, 5 Aug 2019 19:33:09 +0200 Subject: soc/intel/{cnl,icl}: Use new power-failure-state API pmc_soc_restore_power_failure() is only called from SMM, so add `pmc.c` to the `smm` class. Once all platforms moved to the new API, it can be implemented in a central place, avoiding the weak- function trap.
