Exactly.  Since the existing erase block calls are not
doing whole-chip erasure ... and since chip-erase is
a *VERY* different operation.

The MTD interface just says "erase this stuff", and
that patch just added a special case "if <stuff> is
the whole chip, use this operation instead of the
existing iterate-over-blocks logic".
