e2d671d597 hv/trace_mesa.py: add mesa tracer 
Mesa is Apple's codename for the TouchID sensor. On M1-based
systems, it is connected to the SPI bus and communicates via
SIO on DMA channels 0x18 and 0x19. The application processors
seem to have very little to do with its operation.

After power on, the command buffer is encrypted by the SEP and
very little useful data can be gleaned from snooping the SIO
messages. While the commands are garbled by the SEP, we can see
that it has a few recurring themes:

* A power on routine involving some sort of calibration, perhaps
  to get a noise image to subtract from each fingerprint

* A polling mode where it is kicked by the kernel and acks if
  there's no finger on the sensor (runs while macOS waits for a
  print)

* A data transfer mode, where a SIO message is sent to an unmapped
  EP and the fingerprint scanned into memory. Likely triggered by
  an interrupt coming off the finger detection ring, but I haven't
  been able to verify this.

8eeb7966aa hv: Refactor CPU switch logic, make hv.cpu() not exit shell 
Get rid of the hv_rearm() thing (which was always a bit dodgy) and
instead properly make sure that all CPUs rendezvous when needed and
switch the active proxy thread without ever exiting exception context.

The Python side can now switch proxy context (by waiting directly for
a proxy boot) without having to exit out of the hypervisor callback,
so cpu() now works as a normal Python method.

Add a cpus() iterator so you can do things like:

>>> for i in cpus(): bt()

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.
