From c148f24c15743a02e855636e6bed013bd121f7f2 Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Thu, 15 May 2008 21:29:04 -0500 Subject: PPC: Change lib_ppc/bat_rw.c to use high bats Currently, this code only deals with BATs 0-3, which makes it useless on systems that support BATs 4-7. Add the support for these registers.
