From 2bf3016f89344d4cd8b2c96bbec2b642a2bde413 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 10 Jul 2008 01:09:23 +1000 Subject: powerpc: Fix problems with 32bit PPC's running with >= 4GB of RAM This patch enables 32bit PPC's (with 36bit physical address space, e.g. IBM/AMCC PPC44x) to run with >= 4GB of RAM. Mostly its just replacing types (unsigned long -> phys_addr_t). Tested on an AMCC Katmai with 4GB of DDR2.
