[U-Boot-Users] [PATCH 02/25] include/configs: Use new CONFIG_CMD_* in 82xx board config files.

Um, yeah, I saw that too. :-)

So, I've been pretty faithful in following the command selection
that is already in the board files so far.  As you have noticed,
one of the effects of this work is that we get to more easily
identify, um, oportunities for improvment...

And yes, I am absolutely relying on _other_ people to test
this set of changes!  I've been checking some of the PowerPC
boards, but that's really all I can do here...

Right.  My plan is this:

    1) Continue with the remaining board config
       files I've not converted yet.
    2) Drink.
    3) Remove uses of CONFIG_COMMAND from the _entire_
       rest of the code base.
    4) Drink.
    5) Cleanup stragglers, fix typos (!), READMEs, etc.
    6) Profit.

I would encourage folks to read through their favorite config files
in the testing tree and make sure it is sane, compiles, or even boots.
If you want to then fix stuff, please submit it against "testing" so
we can be pretty sure it is working there before pulling it into
the mainline repo.

I'm not convinced there is, long term.  However, like I said,
I am currently doing the straight-forward conversion right now.
We can (and should) fix the fallout.  I am in favor of removing
the "config_cmd_all.h" file. That would be step 5), above.

And in the meantime, patches against the testing repo are welcome too!

I hear you. :-)
