The PSCI area should be reserved in Linux for PSCI operations such as suspend/resume. Reserve 2MiB of memory which matches the area used by ATF (BL1, BL2, BL3x, see [1] in ATF source code). This covers all PSCI code and data area and is 2MiB aligned, which is required by Linux for huge pages handling. Please note that this is a default setup allowing to perform PSCI operations with legacy bootloaders. Recent bootloaders should update the region size/position accordingly.

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.
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.
