0ba2027e5e proxyclient: tools: add a FreeBSD loader 
The differences are documented in the script itself, but the main odd
bit is that we pass the provided kernel as an initramfs.  Our modified
loader will probe for the initramfs start/end props in FDT and put up
a memdisk that we load the kernel from.  This choice was made for two
reasons:

1.) Avoid ad-hoc interpretations of a memory region in m1n1, it doesn't
    care if we actually passed it an initramfs or not anyways.

2.) We already had some code on hand to do this in our loader, so I
    suspect we've done similar shenanigans elsewhere anyways.

This also requires a U-Boot change to allow bootefi of an arbitrary
location, as long the size is provided.

The alignment constraints for loader/kernel were kept arbitrarily.  The
kernel will be bounced anyways by loader. I don't recall what
alignment requirements UEFI payloads have, but 2M seems reasonable.

3b68165900 proxyclient: tools: fix linux U-Boot support 
-t is optional, we may not have a tty_dev, so we can avoid trying to
grab the baudrate from it if it's unspecified.

We don't want to use dtb_addr for booti; this is the unmodified payload.
m1n1 will load it and add bits to it at a separate address for passing
on to U-Boot.  For booti purposes, we actually want the augmented FDT
rather than the user-specified.

d0ce92a284 pcie: Set correct link speed for 10gb ethernet 
The PCIe 4 link speed is only described as "target-link-speed" in the
"lan-10gb". This changed in macos 12.3 or earlier. Verified on Mac
Studio and with the template Mac Mini ADT.
