Subject: [PATCH v4 6/8] ARM: tegra: Always boot CPU in ARM-mode
Date: Mon, 18 Feb 2019 03:17:24 +0300	[thread overview]
Message-ID: <20190218001726.16785-7-digetx@gmail.com> (raw)
In-Reply-To: <20190218001726.16785-1-digetx@gmail.com>

CPU always jumps into reset handler in ARM-mode from the Trusted
Foundations firmware, hence let's make CPU to always jump into kernel
in ARM-mode regardless of the firmware presence. This is required to
make Thumb-2 kernel working with the Trusted Foundations firmware on
Tegra30.
