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 [1], 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.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
