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 I see you have an out-of-date repo on git.kernel.org, can you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
