From a2d4062d427d18127707306dada5e79d69bd3691 Mon Sep 17 00:00:00 2001 From: Naresh G Solanki Date: Tue, 30 Aug 2016 20:47:13 +0530 Subject: soc/intel/skylake: Add FSP 2.0 support in ramstage Add FSP 2.0 support in ramstage. Populate required Fsp Silicon Init params and configure mainboard specific GPIOs. Define function fsp_soc_get_igd_bar needed by fsp2.0 driver for pre OS screens.
