From: Marc Reilly <marc@cpdesign.com.au> To: barebox@lists.infradead.org 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.
