This patch implements `.final` hooks for the IGD device to perform the
required operations before handing the control to the payload or OS.
The MBUS (Memory Bus) is a high-speed interface that connects the
graphics controller to the system memory. It provides a dedicated data
path for graphics data, which helps to improve graphics performance.
The MBUS is a key technology that helps to make the Intel i915 driver
powerful and versatile graphics drivers available. It provides the
high-speed data transfer capabilities that are essential for smooth
and responsive graphics performance.
Enable this config to ensure that the Intel GFX controller joins the
MBUS before the i915 driver is loaded. This is necessary to prevent
the i915 driver from re-initializing the display if the firmware has
already initialized it. Without this config, the i915 driver will
initialize the display to bring up the login screen although the
firmware has initialized the display using the GFX MMIO registers and
framebuffer.
Kernel graphics driver can avoid redundant display init by firmware,
which can optimize boot time by ~15ms-30ms.
Ensures hashing mode is 1x4 to enable a single pipe between Pipe A or B.
Typically, internal display is on Pipe-A, so 1x4 restricts MBUS joining
to internal display alone.

This script lists all new commits from users with few merged commits.
By default, it looks at the last week, and considers anyone with fewer
than 5 commits merged to be a new user.
Currently the only command line argument that's accepted is the gerrit
username of the person running the query. To modify any of the other
options, the values hard-coded into the script need to be updated.
To keep down the number of repeated queries, the script saves lists of
users considered to be experienced, as well as the commits from new
users that it lists.

This patch adds support for detecting dual displays (eDP and HDMI) on

Reserve SBREG BAR if it is outside of the PCH reserved memory range.
Desktop series processors have larger SBREG BARs, which, unlike mobile
processors, do not fall into the standard PCH reserved range
(0xfc800000 - 0xfe7fffff). Create a separate reservation for such a case. There is no telling what could happen if the reservation is not
made in ACPI.

On ICH9 the SPI control register is not naturally aligned
and a word write might be split into smaller naturally aligned
I/O transactions.
As the first byte starts a new SPI transfer, replace the existing
word write with two byte writes and write the second byte first.
This is required for platforms that do not support unaligned
word I/O instructions and would start a SPI transfer while the
second byte hasn't reached the control register yet.
TEST: Virtual SPI controller on qemu 8.0 doesn't start a transfer
early.
