From a5986432679205df5f80f7699f7853a0e7e5a509 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 24 Aug 2011 09:14:16 -0500 Subject: [PATCH] powerpc/85xx: Cleanup how SVR_MAJ() is defined on MPC8536 The MPC8536 seems to use only 3 bits for the major revision field in the SVR rather than the 4 bits used by all other processors. The most significant bit is used as a mfg code on MPC8536.
