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. TEST= Build and Boot Kunimitsu with PLATFORM_USES_FSP1_1 Build and Boot Kunimitsu to romstage with PLATFORM_USES_FSP2_0 Change-Id: I4309c8d4369c84d2bd1b13e8ab7bfeaaec645520 Signed-off-by: Rizwan Qureshi <rizwan.qureshi@intel.com> Reviewed-on: https://review.coreboot.org/16267 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins)
