From: Arnd Bergmann <[email protected]>
This board was an early prototype platform for early SH4 CPUs and related
to the already removed SH5 cayman platform.
The microdev board itself has been kept in the tree for this long despite
being in a bad shape even 20 years ago when it got merged, with no working
PCI support and ugly workarounds for its I/O port implementation that
try to emulate PC style peripheral access despite being quite different
in reality.
As far as I can tell, the ethernet, display, USB and PCI devices on it
already broke at some point (afbb9d8d5266b, 46bc85872040a), so I
think we can just remove it entirely.

2.39.2
From: Arnd Bergmann <[email protected]>
These functions were only used on the microdev
board that is now gone, so remove them to simplify
the ioport handling.
This could be further simplified to use the generic
I/O port accessors now.

2.39.2
From: Arnd Bergmann <[email protected]>
superhyway was only referenced on sh4-202, which is now gone, so remove
it all as well.
I could find no trace of anything ever calling
superhyway_register_driver(), not in the git history but also not on the
web, so I assume this has never served any purpose on mainline kernels.

2.39.2
From: Arnd Bergmann <[email protected]>
This early prototype of the SH4 CPU was only used in

sh4-202 supoprt can also be removed.
