Subject: [PATCH v2 09/15] ARM: qcom: Add qcom,msm8916-smp enable-method identical to MSM8226
Date: Mon,  4 Oct 2021 22:49:49 +0200	[thread overview]
Message-ID: <20211004204955.21077-9-stephan@gerhold.net> (raw)
In-Reply-To: <20211004201921.18526-1-stephan@gerhold.net>

Unfortunately, some MSM8916 devices have signed firmware without
ARM64 and PSCI support and can therefore only boot ARM32 Linux.
The ARM Cortex-A53 cores should be actually booted exactly like
the Cortex-A7 cores on MSM8226, so just add an alias for the
existing code.
