[PATCH 2/7] tegra: remove debug_ll

Subject: [PATCH 2/7] tegra: remove debug_ll
Date: Fri,  1 Mar 2013 10:22:48 +0100	[thread overview]
Message-ID: <1362129773-4579-3-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1362129773-4579-1-git-send-email-dev@lynxeye.de>

Without some kind of initialisation those LL debug functions are mostly
useless. We might want them when booting from the AVP, but for this to
work they need some serious rework, so move them out of the way for now.
