From 8e4654527ef5fec658ca5aacad0612653d3dcf30 Mon Sep 17 00:00:00 2001 From: Sridhar Siricilla Date: Mon, 23 Sep 2019 20:59:38 +0530 Subject: soc/intel/{common,skl,cnl,icl,apl,tgl}: Move HFSTS1 register definition to SoC Below changes are implemented: 1. Move HFSTS1 register definition to SoC since HFSTS1 register definition is specific to a SoC. Moving structure back to SoC specific to avoid unnecessay SoC specific macros in the common code. 2. Define a set of APIs in common code since CSE operation modes and working states are same across SoCs. cse_is_hfs1_com_normal(void) cse_is_hfs1_com_secover_mei_msg(void) cse_is_hfs1_com_soft_temp_disable(void) cse_is_hfs1_cws_normal(void) 3. Modify existing code to use callbacks to get data of me_hfs1 structure. TEST=Build and Boot hatch, soraka, tglrvp, bobba and iclrvp boards.
