From 2be8951e145eacf2a951288ea8e752e3b21acefd Mon Sep 17 00:00:00 2001 From: Joseph Lo Date: Fri, 22 Feb 2013 14:24:26 +0800 Subject: [PATCH] ARM: tegra: fix the logical detection of power on sequence of warm boot CPUs The warm boot sequence of Tegra30 secondary CPUs should wait for the power ready then removing the clamps. This did not fix any known or unknown issue, but nice to have this fix.
