[U-Boot] [Patch v2] common: Add get_effective_memsize() to memsize.c

Tue Feb 11 20:57:26 CET 2014
This function has been around for powerpc. It is used for systems with
memory more than CONFIG_MAX_MEM_MAPPED. In case of non-contiguous memory,
this feature can limit U-boot to one block without going over the limit.

Change log:
v1: The function is added to arch/arm/lib/board.c without changing others
v2: The function is moved to common/memsize.c, using __weak. The prototype
is added to include/common.h. Also consolidate existing functions for
powerpc.
