Linus Torvalds 7d0d3fa733 ARM: boardfile deprecation for 6.0 
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.
