We're not using it in the end because we fixed this in Linux, but I went
through the trouble of writing the function so we might as well leave it
lying around.

The SD card reader on Macbook Pro 14"/16" and Mac Studio uses yet
another property to override the port's "maximum-link-speed" property.
Add parsing for "expected-link-speed" and always look in the port's
first child for these properties.
Increases the link speed to PCIe 2.0 which is required for the full
bandwidth of SDXC UHS-II.

Fixes a copy and paste error in 1b5dee2496 checking dart-dcp twice.

Additional L2 tables for dart-dcp/disp0 need to be from carveout memory
so they can kept after m1n1 exist. iboot has "pt-region-X" and "l2-tt-X"
in the ADT. For DCP on M2 we have to start installing them at "vm-base"
which is 0x8_0000_0000.
This probably causes problems on M2 Pro which uses 1 << 40 as vm-base
for dart-dcp0.

U-Boot is moving to a new set of tags to indicate devices that
should be bound/probed in early bootstrap phases. Add 'bootph-all'
tags from the new bindings such that probing the serial port
early on in U-Boot continues to work and doesn't hang the system.

This is in preparation for the next commit to use "framebuffer" as
compatible string for the boot framebuffer. This is in line with a
proposed change for boot framebuffer handling on Nvidia Tegra SoCs.
It will allow removing simpledrm via
drm_aperture_remove_conflicting_framebuffers().

The main part of function will be used to add a reserved memory region
for the framebuffer from "/vram" instead of the carveout.

Add some minimal implementation of virtio peripherals. At the level
of on-target hypervisor code we implement the MMIO layout and
maintain virtqueues. Once a buffer is available, we break into the
host proxyclient to deal with it.
Specific device-classes of the virtio spec ought to be implemented in
the proxyclient. Here the one device implemented is 9P transport,
exporting the m1n1 source directory.

This includes mapping it to 12.3.0 for compat in both DCP and GPU.
Added for machines with replaced logic boards that trigger the 12.3
bootloop issue.
Also fix the 12.5/12.6 version arrays which were wrong.

dcp_txt is mapped on dart-dcp and dart-dcpext so check if its reserved

This avoids having duplicate calls for dcpext* on each mayor SoC
variant. Fixes setting firmware versions for dcpext on t8103 and t8112.
