[PATCH v4 0/5] Refactor common Kconfigs for easier maintenance

Common Kconfig options which depend on a long list of board- and
SoC- specific Kconfigs can be cumbersome to maintain, leading to
annoying merge conflicts (although rather trivial ones).
This series factors out the dependencies of CACHE_L2X0 and SMP so
that the knowledge about when these can be enabled is moved to the
relevant board/SoC Kconfig files instead. New
MIGHT_HAVE_CACHE_L2X0 and HAVE_SMP options are defined to mediate
This series has been substantially reworked compared with the
previous post, and is now in two parts:
* The first two patches simply refactor the way the Kconfig
options for CACHE_L2X0 and SMP are implemented, without
making any other changes.
* The final three patches apply functional changes suggested by
the contributors to this series, to make the config
dependencies more correct for some specific boards.
Thanks to Rob Herring, Shawn Guo and Russell King for their
contributions to this series.
I have briefly build-tested on some of the affected boards, but any
further reviews or Tested-Bys would be much appreciated.
