The behavior of the MMP platform code depends on whether the CPU_PXA168/CPU_PXA910/CPU_MMP2 symbols are enabled or not. I believe the intention here was that these can be left disabled for a pure DT-only build, but it's not clear if that actually works. At the minimum, the cpu_is_pxa168() and cpu_is_pxa910() checks behave differently, which causes changes in the power management code. For the moment, make the behavior depend on whether CONFIG_ATAGS is set or not, to make it easier to bisect the removal of the old code later. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
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.
