From 095f695cbb07281682462da0618fffabb499d0be Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Tue, 19 Aug 2008 12:50:31 -0500 Subject: [PATCH] ssb: Update for Rev. 5 SPROM Although a revision 5 SPROM has not been seen in the wild, the open-source portion of the MIPS driver 4.150.10.5 describes its layout, which is mostly inherited from revision 4. This patch implements the differences. Signed-off-by: Larry Finger Acked-by: Michael Buesch Signed-off-by: John W.
