Pull sh updates from John Paul Adrian Glaubitz:
"While the previously announced patch series for converting arch/sh to
device trees is not yet ready for inclusion to mainline and therefore
didn't make it for this pull request, there are still a small number
changes for v6.7 which include one platform (board plus CPU and driver
code) removal plus two fixes.
The removal sent in by Arnd Bergmann concerns the microdev board which
was an early SuperH prototype board that was never used in production.
With the board removed, we were able to drop the now unused code for
the SH4-202 CPU and well as the driver code for the superhyway bus and
a custom implementation for ioport_map() and ioport_unmap() which will
allow us to simplify ioport handling in the future.
Another patch set by Geert Uytterhoeven revives SuperH BIOS
earlyprintk support which got accidentally disabled in
e76fe57447 ("sh: Remove old early serial console code V2"), the
second patch in the series updates the documentation.
Finally, a patch by Masami Hiramatsu fixes a regression reported by
the kernel test robot which uncovered that arch/sh is not implementing
arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local()
instead"

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.
