Merge tag 'arm-boardfile-remove-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC boardfile updates from Arnd Bergmann
 "Unused boardfile removal for 6.3

  This is a follow-up to the deprecation of most of the old-style board
  files that was merged in linux-6.0, removing them for good.

  This branch is almost exclusively dead code removal based on those
  annotations. Some device driver removals went through separate
  subsystem trees, but the majority is in the same branch, in order to
  better handle dependencies between the patches and avoid breaking
  bisection.

  Unfortunately that leads to merge conflicts against other changes in
  the subsystem trees, but they should all be trivial to resolve by
  removing the files.

  See commit 7d0d3fa7339e ("Merge tag 'arm-boardfiles-6.0' of
  git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
  description of which machines were marked unused and are now removed.

  The only removals that got postponed are Terastation WXL (mv78xx0) and
  Jornada720 (StrongARM1100), which turned out to still have potential
  users"
