Finn Thain c03effc478 m68k: mac: Fix reboot hang on Mac IIci
[ Upstream commit 265a3b322df9a973ff1fc63da70af456ab6ae1d6 ]

Calling mac_reset() on a Mac IIci does reset the system, but what
follows is a POST failure that requires a manual reset to resolve.
Avoid that by using the 68030 asm implementation instead of the C
implementation.

Apparently the SE/30 has a similar problem as it has used the asm
implementation since before git. This patch extends that solution to
other systems with a similar ROM.

After this patch, the only systems still using the C implementation are
68040 systems where adb_type is either MAC_ADB_IOP or MAC_ADB_II. This
implies a 1 MiB Quadra ROM.

This now includes the Quadra 900/950, which previously fell through to
the "should never get here" catch-all.

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.
