Subject: [PATCH v2 5/5] ARM: tegra: Always boot CPU in ARM-mode
Date: Tue, 19 Jun 2018 14:00:27 +0300 [thread overview]
Message-ID: <20180619110027.16935-6-digetx@gmail.com> (raw)
In-Reply-To: <20180619110027.16935-1-digetx@gmail.com>
CPU always jumps into the reset handler in ARM-mode from the Trusted
Foundations firmware, hence make CPU to always jump into kernel in
ARM-mode regardless of the firmware presence to support Thumb2 kernel + TF
case.
