add_tracer()'s argument of the same name.

c746549c2e hv: Map RAM via tracer infra, handle carveouts in Python 
Previously RAM was mapped ad-hoc, but this can end up interacting
poorly with the tracer infrastructure which we are now using for RAM
too. Move to mapping guest RAM via the tracer infra, and also unmap the
TZ carveouts in the Python side so it knows about them.

This is a HV ABI break.

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.

df53f16f76 m1n1.hv: Copy /chosen/memory-map/preoslog if it exists 
preoslog was added in macos 12.3 and seems to contain iBootStage1 log
output. Since macos 12.3 accesses it it has to be copied to after the
guest image.

5e5b83e7a2 m1n1.hw.nco: Add NCO driver 
Apple SoCs have an NCO block used for generating audio master clocks.

The block performs fractional division of a higher-rate input clock and
contains a counter which is partially implemented as a LFSR. Credit
goes to Hector for reversing the divisor register semantics.
