Subject: [PATCH 5/7] [POWERPC] mpc85xx_mds: reset UCC ethernet properly
Date: Fri, 5 Oct 2007 21:46:47 +0400	[thread overview]
Message-ID: <20071005174647.GC32145@localhost.localdomain> (raw)
In-Reply-To: <20071005174015.GA11016@localhost.localdomain>

Apart from that the current code doesn't compile it's also
meaningless with regard to the MPC8568E-MDS' BCSR.

This patch used to reset UCCs properly.
