Add frame to call fspsinit.<br>2. Temporary clear all the USB OC pin to 0 to pass FSP siliconinit.<br><br>Change-Id: I1c9c35ececf3c28d7a024f10a5d326700cc8ac49<br>Signed-off-by: Lijian Zhao <lijian.zhao@intel.com><br>---<br>M src/soc/intel/cannonlake/Makefile.inc<br>A src/soc/intel/cannonlake/chip.c<br>A src/soc/intel/cannonlake/chip.h<br>A src/soc/intel/cannonlake/include/soc/ramstage.h<br>4 files changed, 121 insertions(+), 0 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://review.coreboot.org:29418/coreboot refs/changes/81/20581/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">diff --git a/src/soc/intel/cannonlake/Makefile.inc b/src/soc/intel/cannonlake/Makefile.inc<br>index a5cb463..2b5bd1c 100644<br>--- a/src/soc/intel/cannonlake/Makefile.inc<br>+++ b/src/soc/intel/cannonlake/Makefile.inc<br>@@ -16,6 +16,7 @@<br> romstage-y += reset.c<br> romstage-$(CONFIG_DRIVERS_UART_8250MEM) += uart.c<br> <br>+ramstage-y += chip.c<br> ramstage-y += memmap.c<br> ramstage-$(CONFIG_PLATFORM_USES_FSP2_0) += reset.c<br> ramstage-$(CONFIG_DRIVERS_UART_8250MEM) += uart.c<br>diff --git a/src/soc/intel/cannonlake/chip.c b/src/soc/intel/cannonlake/chip.c<br>new file mode 100644<br>index 0000000..70b4718<br>--- /dev/null<br>+++ b/src/soc/intel/cannonlake/chip.c<br>@@ -0,0 +1,61 @@<br>+/*<br>+ * This file is part of the coreboot project.<br>+ *<br>+ * Copyright (C) 2016-2017 Intel Corporation.<br>+ *<br>+ * This program is free software; you can redistribute it and/or modify<br>+ * it under the terms of the GNU General Public License as published by<br>+ * the Free Software Foundation; version 2 of the License.<br>+ *<br>+ * This program is distributed in the hope that it will be useful,<br>+ * but WITHOUT ANY WARRANTY; without even the implied warranty of<br>+ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
