From b40f734af9fdc47a0993f1f94f32d40a86f30587 Mon Sep 17 00:00:00 2001 From: Tom Warren Date: Mon, 1 Apr 2013 15:48:54 -0700 Subject: Tegra114: Initialize System Counter (TSC) with osc frequency T114 needs the SYSCTR0 counter initialized so the TSC can be read by the kernel. Do it in the bootloader since it's a write-once deal (secure/non-secure mode dependent).
