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.

To make a system for gth that actually works ;-)
the variable TBASE needs to be set to 0,1 or 2
depending on location where image is supposed to
be started from.
E.g. make TBASE=1

0: Start from RAM, base 0

1: Start from flash_base + 0x10070

2: Start from flash_base + 0x30070

When using 1 or 2, the image is supposed to be launched
from miniboot that boots the first U-Boot image found in
flash.
