Subject: [PATCH] [UPDATED] tsec: Allow Ten Bit Interface to be configurable

From: Joe Hamman <[email-masked]>
Date: Mon, 13 Aug 2007 17:37:49 -0500

Allow the address of the Ten Bit Interface (TBI) to be changed in the
event of a conflict with another device.

Signed-off by: Joe Hamman <[email-masked]>

Please ignore the last patch - I missed a cut & paste error on the range
that my testing didn't catch.
