[U-Boot] [RFC PATCH 0/4] cmd: Simplify support for sub-commands

[Boris Brezillon]

Hello,

This patch series aims at simplifying the command parsing logic done in
pretty much all the cmd/foo.c files by adding a few macros that help
defining sub-commands attach to the main entry point.

When you use those macros you also get sub-command auto-completion for
free (the rest of the auto-completion still has to be done manually).

Support for several levels of sub commands is not supported but can
easily be added if needed.

Some details about the patches:

- Patch 1 is a fix for the auto-completion code that I had to do have
  auto-completion in the mtd command working correctly (I can submit it
  separately if needed)
- Patch 2 is exposing a function to ease support of auto-completion of
  sub-commands
- Patch 3 is adding a set of macros to easily declare the sub-commands
  attached to the main command
- Patch 4 is making use of this new infrastructure in cmd/mtd.c.

Regards,

Boris
