Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code on bigendian machines. Also set the quirk_addfb_prefer_host_byte_order mode_config bit so drm_mode_addfb() asks for the correct format code. Create our own plane and use drm_crtc_init_with_planes() instead of depending on the default created by drm_crtc_init(). That way the plane format list is correct on bigendian machines. Also re-add the framebuffer format check dropped by "df2052cc92 bochs: convert to drm_fb_helper_fbdev_setup/teardown". With this patch applied both ADDFB and ADDFB2 ioctls work correctly in the bochs-drm.ko driver on big endian machines. Without the patch only ADDFB (which still seems to be used by the majority of userspace) works correctly.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
