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. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
