Pull ARM boardfile deprecation from Arnd Bergmann:
 "Over the past ten years, new machine support was based on device tree,
  and an initial set of about 400 boards using ATAGS with boardfile for
  booting were grandfathered in, with about half of them either removed
  or converted to DT over time.

  Based on the recent mailing list discussion I started, I have now
  turned the findings into a set of patches that marks most board files
  as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.

  For the boards that are marked as unused, there are two final chances
  for potential users: The removal is scheduled to take place after the
  longterm stable kernel at the end of 2022, so users can stay on that
  version for another few years, and if anyone still has one of these
  machines and is planning to keep updating kernels beyond that version,
  they can speak up now to have their boards taken off the list again.

  Waiting for the LTS release also makes sure that there will be at
  least one longterm kernel that contains the recent multiplatform
  conversion along while still supporting all legacy boards.

  The short summary of the current status is:

   - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
     users and will be removed entirely.

   - The mmp and davinci platforms have DT support for the important
     machines and will become DT-only after this.

   - s3c64xx, dove, orion5x, and pxa keep some board files to allow
     those to be migrated over to DT more easily, but most board files
     are getting removed now. DT support on these platforms is partially
     working but requires changes to additional drivers for the other
     boards.

   - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the
     moment but have some boards with known users. Removing the board
     files that nobody uses should make it easier to try a DT conversion
     if anyone cares.

  There is no explicit timeline what happens with the boards that remain
  after this removal, but I expect to revisit this in the future, and
  with most boards gone, there will be a good time to do a treewide
  review of platform drivers that never gained DT support and have no
  remaining in-tree board files"
