From 3ca64d0669b467e951d6020f154a7fd8810db35b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 14 Sep 2023 17:55:20 +0200 Subject: sh: Remove stale microdev board 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 removeit entirely.

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.
