soc/intel/tigerlake: Update fsp_params for TGL
Add initial fsp upd settings for TGL, both romstage and ramstage upd's to support basic build and boot of TGL RVP. - Add Silicon upd settings which includes * Serial IO/UART settings * Graphics settings * USB2/USB3 settings - Add Romstage upd settings which includes * Pcie Root port settings * IGD initialization * Hyper Threading settings * SMBus controller settings * Debug probe settings BUG=none BRANCH=none TEST=Build and boot Tigerlake rvp board Signed-off-by: Srinidhi N Kaushik <srinidhi.n.kaushik@intel.com> Change-Id: I16df66451fd3a681df1222d283d97dd6bdaff0e9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/37960 Reviewed-by: Wonkyu Kim <wonkyu.kim@intel.com> Reviewed-by: Subrata Banik <subrata.banik@intel.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
