WoA devices using x1e/x1p use android firmware to boot, which notably includes Gunyah hypervisor. This means that, so far, Linux-based OS could only boot in EL1 on those devices. However Windows can replace Gunyah upon boot with it's own hypervisor, and with the use of tools such as "slbounce", it's possible to do the same for Linux-based OS, in which case some modifications to the DT are necessary to facilitate the absence of Gunyah services. Add a EL2-specific DT overlay and apply it to x1e/x1p WoA devices to create -el2.dtb for each of them alongside "normal" dtb.

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.
