From 3658c629086754fd4ad66d64f7d9862acfe31ef5 Mon Sep 17 00:00:00 2001 From: Jamie Chen Date: Tue, 10 Mar 2020 16:50:53 +0800 Subject: soc/intel/cannonlake: Add configs for USB 3.1 Gen2 EV settings Add configs for USB 3.1 Gen2 EV settings so that people can set the EV settings per board in device tree. BUG=b:150515720 BRANCH=none TEST=build coreboot and fsp with enabled fw_debug. Flashed to puff and checked the log. All usb configs were set correctly.
