Subject: [PATCH 17/30] tegra: hardcode entry address for main cluster
Date: Tue,  3 Jun 2014 22:35:04 +0200	[thread overview]
Message-ID: <1401827717-6420-18-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1401827717-6420-1-git-send-email-dev@lynxeye.de>

I don't know why get_runtime_offset fails on T124 yet,
but this is a safe workaround, with the nice side-effect
of fixing second stage barebox loading.
