so this commit started producing warnings for boards that defined their
own CONFIG_MAX_MEM_MAPPED, such as the SIMPC8313 (with 512MB):

commit 87c9063963561d3d01064be34d0c30855a56587b

    ppc: Move CONFIG_MAX_MEM_MAPPED to common config.h
    
    Moved CONFIG_MAX_MEM_MAPPED to the asm/config.h so its kept consistent
    between the two current users (lib_ppc/board.c, 44x SPD DDR2).

the warnings are:

In file included from /home/r1aaha/git/u-boot/include/config.h:5,
                 from /home/r1aaha/git/u-boot/include/common.h:35,
                 from simpc8313.c:26:
/home/r1aaha/git/u-boot/include/configs/SIMPC8313.h:81:1: warning: "CONFIG_MAX_MEM_MAPPED" redefined

/home/r1aaha/git/u-boot/include/asm/config.h:28:1: warning: this is the location of the previous definition

which is probably all due to include/config.h including the file with
the default value prior to the board's config:

/* Automatically generated - do not edit */
#include <asm/config.h>
#include <configs/SIMPC8313.h>

So how are boards supposed to define their own CONFIG_MAX_MEM_MAPPED
now?  In the Makefile?  Or is there a better place for this default
value?
