From ff945023c6a455679165b14d298316e262ceeb1f Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Sat, 28 May 2005 15:52:14 -0700 Subject: [PATCH] ppc32: MPC834x BCSR_SIZE too small for use in a BAT. The call to io_block_mapping was creating an invalid BAT entry because the value of BCSR_SIZE (32K) is too small to be used in a BAT (128K min). This change removes the io_block_mapping call since these registers can easily be mapped using ioremap at the point of use.
