As of commiteae06120f1("drm: refuse ADDFB2 ioctl for broken bigendian drivers"), drivers must set the quirk_addfb_prefer_host_byte_order quirk to make the drm_mode_addfb() compat code work correctly on big-endian machines. While that works fine for big-endian XRGB8888 and ARGB8888, which are mapped to the existing little-endian BGRX8888 and BGRA8888 formats, it does not work for big-endian XRGB1555 and RGB565, as the latter are not listed in the format database. Fix this by adding the missing formats. Limit this to big-endian platforms, as there is currently no need to support these formats on little-endian platforms. Fixes:6960e6da9c("drm: fix drm_mode_addfb() on big endian machines.")

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.
