Powerpc 601 is rather old powerpc which as some important limitations compared to other book3s/32 powerpcs: - No Timebase. - Common BATs for instruction and data. - No execution protection in segment registers. - No RI bit in MSR - ... It is starting to be difficult and cumbersome to maintain kernels that are compatible both with 601 and other 6xx cores. Create a compiletime option to exclusively select either powerpc 601 or other 6xx.

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.
