Currently, Panfrost only supports MMU configuration in "LEGACY" (as Bifrost calls it) mode, a (modified) version of LPAE "Large Physical Address Extension", which in Linux we've called "mali_lpae". This commit adds support for conditionally enabling AARCH64_4K page table format. To achieve that, a "GPU optional quirks" field was added to `struct panfrost_features` with the related flag. Note that, in order to enable AARCH64_4K mode, the GPU variant must have the HW_FEATURE_AARCH64_MMU feature flag present.

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.
