On gen11 we only needed to program MBus credits into MBUS_ABOX_CTL during display initialization, but on gen12 we're now supposed to program the same values into MBUS_ABOX1_CTL and MBUS_ABOX2_CTL as well. v2: - Program registers with rmw to preserve contents of unrelated bits. - Switch to the new display uncore helpers.

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.
