Becky Bruce 9973e3c614 Change initdram() return type to phys_size_t
This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory.  phys_size_t is defined as an unsigned long on almost
all current platforms.

This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram).  It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.

Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

----------------------------------------
Qemu is a full system emulator. See

http://fabrice.bellard.free.fr/qemu

Limitations & comments
----------------------
Supports the "-m mips" configuration of qemu: serial,NE2000,IDE.
Support is big endian only for now (or at least this is what I tested).
Derived from au1x00 with a lot of things cut out.

Supports emulated flash (patch Jean-Christophe PLAGNIOL-VILLARD) with
recent qemu versions. When using emulated flash, launch with
-pflash <filename> and erase mips_bios.bin.
