From 33ff4cc137e501b14859bc67cc7e85dd60a863cc Mon Sep 17 00:00:00 2001 From: Usha P Date: Thu, 28 Nov 2019 10:05:45 +0530 Subject: soc/intel/cannonlake: Refactor pch_early_init() code This patch keeps required pch_early_init() function like ABASE programming, GPE and RTC init into bootblock and moves remaining functions like TCO configuration and SMBus init into romstage/pch.c in order to maintain only required chipset programming for bootblock and verstage. Rename the pch_init function to bootblock_pch_init and romstage_pch_init according to the stage it is defined in. TEST=Able to build and boot hatch successfully.
