Subject: [U-Boot] [PATCH 7/7] arm: change arm720t to armv4t
Date: Fri, 6 Jul 2012 11:09:02 -0700 [thread overview]
Message-ID: <1341598142-28873-8-git-send-email-amartin@nvidia.com> (raw)
In-Reply-To: <1341598142-28873-1-git-send-email-amartin@nvidia.com>
arm720t is an armv4t not an armv4. Force some tegra initialization
functions to arm mode because they contain arm only inline assembly.
