[PATCH 1/2] sh: remove sh5 support

From: Arnd Bergmann
Date: Mon Apr 20 2020 - 08:39:27 EST

sh5 never became a product and has probably never really worked.

Remove it by recursively deleting all associated Kconfig options
and all corresponding files.

For review purposes, this leaves out the files that can now be
removed, in particular

arch/sh/drivers/pci/*-sh5.c
arch/sh/include/asm/*_64.h
arch/sh/include/uapi/asm/*_64.h
arch/sh/include/cpu-sh5/*
arch/sh/kernel/cpu/sh5/*
arch/sh/lib64/*
arch/sh/mm/*-sh5.c
