commit 3c8a9066d584f5010b6f4ba03bf6b19d28973d52 upstream.
PSC controller has a limitation that it can only power-up the second
core when the first core is in ON state. Power-state for core0 should be
equal to or higher than core1.
Therefore, prevent core1 from powering up before core0 during the start
process from sysfs. Similarly, prevent core0 from shutting down before
core1 has been shut down from sysfs.

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.
