[PATCH 02/18] bootm: plan: Drop passing of arguments

[Simon Glass]

It isn't clear how useful it is to pass the arguments of bootm to the
OS. For example, if "bootm 1000 2000 3000" is used, the three arguments
at the end are passed to the OS. This seems like a strange approach,
since the argument have already been parsed by U-Boot and processed.

Rely instead on the "bootargs" mechanism, which is the standard
approach.

Drop the helper function as well.
