From 6a5e69c7ddeacbfcab1ffe501c32e21d7989c0f8 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 20 Apr 2022 09:03:42 +0200 Subject: ARM: s3c: mark as deprecated and schedule removal The Samsung S3C24xx and S3C64xx platforms are very old designs. S3C2416 was introduced in 2008 and S3C6410 in 2009/2010. They are not widely available anymore - out-of-stock on FriendlyArm (one of manufacturers of boards) and only few specialist stores still offer them for quite a high price. The community around these platforms was not very active, so I suspect no one really uses them anymore. Maintenance takes precious time so there is little sense in keeping them alive if there are no real users. Let's mark all S3C24xx and S3C64xx platforms as deprecated and mention possible removal in after 2022 for the first and 2024 for the lattere. The deprecation message will be as text in Kconfig, build message (not a warning though) and runtime print error. If there are any users, they might respond and postpone the removal.
