c2a48da4c1 m1n1.hv: Add trace script keyboard/trackpad
Input devices use HID over SPI. HID communication is obscured by "sio"
DMA.

9c80a69266 m1n1.hv: Use dynamic pin maps in trace_gpio.py
Hardcoded pin maps do not make sense with additional HW support.
Allows tracing of a single pin in another tracing module, for example
for tracing the SPI cs pin.

eb466796d8 fw.dcp: Add some stubs needed for modesetting
This isn't enough to set the video mode yet but it gets us further. I
think allocate_memory/map_buf/powerOnDART need real implementations,
otherwise setting a video mode crashes the DCP in an APIODMA interrupt
handler, whatever that is.

ba478f2de5 mini.hv.dcp: Decode common messages
This accounts for most of the DCP traffic once macOS is booted. I used
a sophisticated side-channel hypervisor timing attack to determine the
message functions [ adding time.sleep(1) ]

edbe471804 run_guest.py: Add options to run external scripts:
-m <script>

  Run a script in hypervisor context prior to starting the guest.
  This is essentially the same as the shell context.

-c <code>
  Run a literal string of code prior to starting the guest.

-S
  Start a shell instead of directly starting the guest. Use `start` to
  actually begin guest execution.

This also adds a couple example scripts under hv/.
