From f59b55a5b8fcadaa99781ba48e7a38e956afa527 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 27 Nov 2007 23:25:02 -0600 Subject: Stop using immap_t for guts offset on 85xx In the future the offsets to various blocks may not be in same location. Move to using CFG_MPC85xx_GUTS_ADDR as the base of the guts registers instead of getting it via &immap->im_gur.
