Subject: [PATCH v2 11/14] secboot: disable falcon interrupts before running
Date: Thu, 27 Oct 2016 13:37:05 +0900	[thread overview]
Message-ID: <20161027043708.22538-12-acourbot@nvidia.com> (raw)
In-Reply-To: <20161027043708.22538-1-acourbot-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Make sure we are not disturbed by spurious interrupts, as we poll the
halt bit anyway.
