True. The upper patch was the quickest way to do this.

I implemented a first test for a command. This is a bit ugly because I
have to rip apart bootm. For now I heavily used extern and removed
static keywords from bootm - this is ok for the testing but not to get
it into mainline...

I'am not sure how i can handle this to get it into mainline. The main
problem is in arch/arm/lib/bootm.c implementation:
static void setup_start_tag (bd_t *bd);
static void setup_memory_tags (bd_t *bd);
static void setup_commandline_tag (bd_t *bd, char *commandline);
static void setup_initrd_tag (bd_t *bd, ulong initrd_start,
                  ulong initrd_end);
static void setup_end_tag (bd_t *bd);
static struct tag *params;
static ulong get_sp(void);
static int bootm_linux_fdt(int machid, bootm_headers_t *images);

These function i need to build the atags. But they are defined static
and not really meant to be used from the outside. What comes to my
mind here is to create a new setup_atags.c in the same directory + a
header in include. Is this the right place for this? Maybe another
solution?
