Subject: [PATCH soc] ARM: BCM5301X: Ignore another (BCM4709 specific) fault code
Date: Wed, 11 Feb 2015 16:40:58 +0100 [thread overview]
Message-ID: <1423669258-27449-1-git-send-email-zajec5@gmail.com> (raw)
Broadcom ARM devices seem to generate some fault once per boot. We
already have an ignoring handler for BCM4707/BCM4708, but BCM4709
generates different code.
