Subject: [PATCH v3 2/6] ARM: tegra: Add chipid, revision and fuse init
Date: Wed, 29 Jan 2014 01:36:12 +0200 [thread overview]
Message-ID: <1390952176-30402-3-git-send-email-pdeschrijver@nvidia.com> (raw)
In-Reply-To: <1390952176-30402-1-git-send-email-pdeschrijver@nvidia.com>
All fuse related functionality will move to a driver in the following patches.
To prepare for this, export all the required functionality in a global header
file and move all users of fuse.h to tegra-soc.h
Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
