I re-tested against master but found a problem. In commit
"5c427e4: use BOOTM_STATE_OS_CMDLINE flag for plain bootm" and "3d187b3: 
Only pass BOOTM_STATE_OS_CMDLINE on PowerPC/MIPS", 
BOOTM_STATE_OS_CMLINE was added to do_bootm for PowerPC and MIPS. This 
breaks other OSes (vxworks, netbsd, plan9,...) that don't support 
subcommand processing, e.g. they all contain the following code in their 
do_bootm_xxx():

if (flag & BOOTM_STATE_OS_PREP)
	return 0;
if ((flag != 0) && (flag != BOOTM_STATE_OS_GO))
	return 1;

which will result a "subcommand not supported" error.   IMO, the above 
code should be converted to something like this:

/* if not go command, pretend everything to be OK */
if (flag != BOOTM_STATE_OS_GO)
     return 0;

And if you are OK with it, I could send patches to clean them up. Thanks.
