From: Eugeniu Rosca <erosca at de.adit-jv.com>
Enriching the functionality of U-Boot 'bcb' may assume using the
existing sub-commands as building blocks for the next ones.
A clean way to achive the above is to expose a number of static
routines, each mapped to an existing user command (e.g. load/set/store),
with a user/caller-friendly prototype (i.e. do not force the caller
to wrap an integer into a string).
This second patch makes '__bcb_set' available for internal needs.
No functional change intended.
