Subject: [PATCH 4/4] ARM: beaglebone: init MPU speed to 800Mhz
Date: Mon, 14 Jun 2021 08:26:39 +1000	[thread overview]
Message-ID: <20210613222639.13190-4-marc@cpdesign.com.au> (raw)
In-Reply-To: <20210613222639.13190-1-marc@cpdesign.com.au>

This sets the core processor speed to 800Mhz (from 500). Doing this helps
speed the boot up a bit until the CPU freq govenor takes over.
