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.

Several board/<...>/config.mk files include dynamically built (by
the Makefile) config files but used the wrong file name of
	$(TOPDIR)/board/$(BOARDDIR)/config.tmp
instead if the correct
	$(OBJTREE)/board/$(BOARDDIR)/config.tmp

The bug is nasty because the build result is correct for the (normal)
in-tree builds, and because 'sinclude' is used no errors get raised
even for out-of-tree build tests. But out-of-tree builds use an
incomplete and thus usually incorrect configuration...

Fixed some broken instances of "#ifdef CMD_CFG_IDE" too.
Those always evaluated TRUE, and thus were always compiled
even when IDE really wasn't defined/wanted.

  - fix a typo in V38B config file
  - move watchdog initialisation earlier in the boot process
  - add "wdt=off" to default kernel command line (disables kernel watchdog)

 - add watchdog support
 - enable GPIO_WKUP_7 pin for input
 - code cleanup

      * remove warnings when compiling ethaddr.c
      * adjust linker script (fixes a crash resulting from incorrect
      definition of __u_boot_cmd_start)
- Some MarelV38B code cleanup.
