From 7bdf39cfafd29fc1192dd1aa997b5937f92a3c74 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Fri, 10 Aug 2018 02:39:38 -0700 Subject: [PATCH] x86: efi: payload: Add default TSC frequency in the device tree It was observed sometimes U-Boot as the EFI 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.
