[PATCH v10 6/7] ARM: tegra: Always boot CPU in ARM-mode

From: Dmitry Osipenko <digetx@gmail.com>
Date: 2019-03-17 22:56:11
Also in: linux-tegra, lkml
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds 

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.
