This patch adds common code used to power down all cores and clusters. The code was previously based on the MCPM framework. It has now been adapted to hook into struct smp_operations directly, but the code structure still shows signs of prior work. The primary core (cpu0) requires setting flags to have the BROM bounce execution to the SMP software entry code. This is done in a subsequent patch to keep the changes cleanly separated. By default the ARM SMP code blocks cpu0 from being turned off, so splitting this out is safe. Signed-off-by: Chen-Yu Tsai <wens@csie.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
