The following changes since commit 77f349b7700f86c51895e36b19dbc5e7323a7dfb: ARM: defconfig: kill remnants of CONFIG_LEDS (2022-07-22 12:34:13 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git tags/arm-boardfiles-6.0 for you to fetch changes up to 1785ab769824b800d7dea83aecc88c90377a6a5d: ARM: cns3xxx: add CONFIG_UNUSED_BOARD_FILES dependency (2022-07-22 14:18:52 +0200) ---------------------------------------------------------------- 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.
