During the upstream progress of those DT-based drivers, DT properties are changed a lot so very different from those in existing bootloaders. It is inevitably that some existing systems do not provide a standard, canonical device tree to the kernel at boot time. So let's provide a device tree table in the kernel, keyed by the dts filename, containing the relevant DTBs. We can use the built-in dts files as references. Each SoC has only one built-in dts file which describes all possible device information of that SoC, so the dts files are good examples during development. And as a reference, our built-in dts file only enables the most basic bootable combinations (so it is generic enough), acts as an alternative in case the dts in the bootloader is unexpected.

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.
