Note that the feature unfortunately only fills in part of the

At present this uses mtrr_add_request() & mtrr_commit() combination
to program the MTRR for graphics memory. This usage has two major
issues as below:
- mtrr_commit() will re-initialize all MTRR registers from index 0,
using the settings previously added by mtrr_add_request() and saved
in gd->arch.mtrr_req[], which won't cause any issue but is unnecessary
- The way such combination works is based on the assumption that U-Boot
has full control with MTRR programming (e.g.: U-Boot without any blob
that does all low-level initialization on its own, or using FSP2 which
does not touch MTRR), but this is not the case with FSP. FSP programs
some MTRRs during its execution but U-Boot does not have the settings
saved in gd->arch.mtrr_req[] and when doing mtrr_commit() it will
corrupt what was already programmed previously.
Correct this to use mtrr_set_next_var() instead.

The Xilinx ZynqMP SoC has a hardened display pipeline named DisplayPort
Subsystem. It includes a buffer manager, blender, an audio mixer and a
DisplayPort source controller (transmitter). The DisplayPort controller can
source data from memory (non-live input) or the stream (live input). The
DisplayPort controller is responsible for managing the link and physical
layer functionality. The controller packs audio/video data into transfer
units and sends them over the main link. The link rate and lane counts can
be selected based on the application bandwidth requirements. The
DisplayPort pipeline consists of the DisplayPort direct memory access (DMA)
for fetching data from memory. The DisplayPort DMA controller (DPDMA)
supports up to six input channels as non-live input.
This driver supports the DisplayPort Subsystem and implements
1)640x480 resolution
2)RGBA8888 32bpp format
3)DPDMA channel 3 for Graphics
4)Non-live input
5)Fixed 5.4G link rate
6)Tested on ZCU102 board
There will be additional work to configure GT lines based on DT, higher
resolutions, support for more compressed video formats, spliting code to
more files, add support for EDID, audio support, using clock framework for
all clocks and in general code clean up.
