Subject: [PATCH 10/12] ARM: tegra: Always lock the CPU reset vector
Date: Fri, 11 Jul 2014 14:16:09 +0200 [thread overview]
Message-ID: <1405080971-7609-11-git-send-email-thierry.reding@gmail.com> (raw)
In-Reply-To: <1405080971-7609-1-git-send-email-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Currently the reset vector is not locked on Tegra20 because the hardware
doesn't support it. However in order not to depend on the chip ID, which
becomes available only later in the boot process, we set the bit anyway.
