Subject: [U-Boot] [PATCH v4 07/13] ARM: Fix arm720t SPL build
Date: Thu, 21 Jun 2012 17:00:41 -0700 [thread overview]
Message-ID: <1340323247-15512-8-git-send-email-amartin@nvidia.com> (raw)
In-Reply-To: <1340323247-15512-1-git-send-email-amartin@nvidia.com>
Take a few SPL fixes from armv7 and apply them to arm720t:
-Use dummy exception handlers for SPL build
-Initialize relocation register r9 to 0 for the case of no relocation
-ifdef out interrupt handler code
