Hi Kumar,

I've been hacking at cmd_bootm.c and image.c.  The direction I'm hacking 
in is:
* Move boot_* stuff from image.c into cmd_bootm.c
   - Calling out to another file to a function unused in that file? Ugly.
* Move the FIT stuff out of image.c into a new file fit_image.c
   - The resulting files are more cohesive and less BIG.
* Move the im* commands out of cmd_bootm.c into a new file cmd_image.c
   - At one time, I was of the opinion that "bootm (loados|ramdisk|fdt)"
       should be "ldimage (os|ramdisk|fdt)".  I'm less sure of myself,
       but have not totally discarded the opinion.
   - Looking in cmd_bootm.c for im* commands is rather unintuitive.

My intent is to do this hacking based on your bootm subcommand changes, 
so we can do a two-step cleanup.

Do you have a git repo I can clone rather than trying to keep up with 
the master repo + your patches?  My tracking of your work is falling 
apart.  I see you have an out-of-date repo on git.kernel.org, can you 
update that perhaps?

Thanks,
gvb
