From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jack Steiner Date: Fri, 18 Nov 2005 15:19:11 +0000 Subject: [PATCH] - SN support for older versions of PROM Message-Id: <20051118151911.GA10918@sgi.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org Add support for old versions of SN PROMs. Eventually this support will be deleted but it is useful right now to continue supporting older PROMs. (The support for older PROMs use to be in the tree. It was deleted by accident).
