Subject: [PATCH 1/4] ARM: cpu: board-dt-2nd: call arm_cpu_lowlevel_init
Date: Mon, 25 Apr 2022 08:28:46 +0200	[thread overview]
Message-ID: <20220425062849.17954-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220425062849.17954-1-a.fatoum@pengutronix.de>

The generic DT image could be started by boot firmware that doesn't do
all the initialization that we do in arm_cpu_lowlevel_init(), so call it
always for good measure. This enables using the generic image as second
stage to the Raspberry Pi videocore.
