From 88cb1a9eb0dc2144d1fe587246820f2d6865b757 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Thu, 23 Mar 2017 23:27:45 +0100 Subject: rockchip: spl: RK3399: add COUNTER_FREQUENCY define to rk3399_common.h The BootROM of the RK3399 SoC does not initialise the cntfrq_el0 (which holds the value 0 (zero) on entry into the SPL. This causes the timebase for U-Boot not to advance (and will cause a hang where a timeout would be expected... e.g. if something goes wrong during MMC/SD card startup). This change defines COUNTER_FREQUENCY, which is used by the AArch64 init code in arch/arm/cpu/armv8/start.S to set up cntfrq_el0 (if necessary).
