From 864915561b3273a4f8894804146d6739e8e49ab2 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Fri, 10 Aug 2018 02:39:37 -0700 Subject: [PATCH] x86: coreboot: Add default TSC frequency in the device tree It was observed sometimes U-Boot as the coreboot payload fails to boot on QEMU. This is because TSC calibration fails with no valid frequency. This adds default TSC frequency in the device tree.
