IPQ5424 supports both TZ and TF-A as secure software options and various DDR sizes. In most cases, TF-A or TZ is loaded at the same memory location, but in the 256MB DDR configuration TF-A is loaded at a different region. So, add the reserved memory node for TF-A and keep it disabled by default. During bootup, U-Boot will detect which secure software is running and enable or disable the node 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 reStructuredText 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.
