Subject[PATCH 4.19 206/306] soc: bcm: brcmstb: Fix re-entry point with a THUMB2_KERNEL
From: Florian Fainelli <>

[ Upstream commit fb14ada11d62fb849fc357a25ef8016ba438ba10 ]

When the kernel is built with CONFIG_THUMB2_KERNEL we would set the
kernel's resume entry point to be a function that is already built as
Thumb-2 code while the boot agent doing the resume is in ARM mode, so
this does not work. There is a header label defined: cpu_resume_arm
which we can use to do the switching for us.
