From 1366e4438d07c2de905454421e18d1e5f68de47d Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Tue, 29 Sep 2020 13:55:50 +0530 Subject: soc/intel: Move pch_enable_ioapic() to common code List of changes: 1. Move pch_enable_ioapic() into common block code. 2. Remove redundant LPC functions from SoC directory and refer from block/lpc directory. TEST=Able to build and boot hatch and tglrvp platform without seeing any functional impact.
