From 1222a73205bd3a0faba988411b4aec6ea8de1059 Mon Sep 17 00:00:00 2001 From: Rizwan Qureshi Date: Tue, 23 Aug 2016 14:31:23 +0530 Subject: skylake: Add initial FSP2.0 support Add Initial pieces of code to support fsp2.0 in skylake keeping the fsp1.1 flow intact. The soc/romstage.h and soc/ramstage.h have a reference to fsp driver includes, so split these header files for each version of FSP driver. Add the below files, car_stage.S: Add romstage entry point (car_stage_entry). This calls into romstage_fsp20.c and aslo handles the car teardown. romstage_fsp20.c: Call fsp_memory_init() and also has the callback for filling memory init parameters. Also add monotonic_timer.c to verstage. With this patchset and relevant change in kunimitsu mainboard, we are able to boot to romstage.
