Merge tag 'arm-platform-removal-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC platform removals from Arnd Bergmann:
 "There are a lot of platforms that have not seen any interesting code
  changes in the past five years or more.

  I made a list and asked around which ones are no longer in use, and
  received confirmation about six ARM platforms and the TI C6x
  architecture that have all reached the end of their life upstream,
  with no known users remaining:

   - efm32 - added in 2011, first Cortex-M, no notable changes after 2013

   - picoxcell - added in 2011, abandoned after 2012 acquisition

   - prima2 - added in 20111, no notable changes since 2015

   - tango - added in 2015, sporadic changes until 2017, but abandoned

   - u300 - added in 2009, no notable changes since 2013

   - zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes

   - arch/c6x - added in 2011, but work stalled soon after that

  A number of other platforms on the original list turned out to still
  have users. In some cases there are out-of-tree patches and users that
  plan to contribute them in the future, in other cases the code is
  complete and works reliably"
