Building ppc40x_defconfig leads to following error
CC arch/powerpc/kernel/idle.o
{standard input}: Assembler messages:
{standard input}:67: Error: unrecognized opcode: `wrteei'
{standard input}:78: Error: unrecognized opcode: `wrteei'
Add -mcpu=440 by default and alternatively 464 and 476.
Once that's done, -mcpu=powerpc is only for book3s/32 now.
But then comes
CC arch/powerpc/kernel/io.o
{standard input}: Assembler messages:
{standard input}:198: Error: unrecognized opcode: `eieio'

Fix it by replacing eieio by mbar on booke.

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.
