From e78b04f9d52642a7284c7df7dbe46651af0c4065 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Thu, 22 Jun 2017 23:31:55 +0200 Subject: [PATCH] rockchip: rk3368: spl: define COUNTER_FREQUENCY to 24MHz The BootROM of the RK3368 Boot ROM does not initialise cntfrq_el0. 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 the counter-frequency is not correctly set up, the calculation of delays using the ARMv8 generic timer can not work correctly.
