98076ef693 usb: disable tps6598x interrupts 
Restore the interrupt masks on chainload or HV guest start. The
interrupt mask is not restored on the USB-C port used by the hypervisor.
This prevents an interrupt storm in the guest when the other USB-C port
is exposed to the guest. Both tps6598x share unfortunately an interrupt
line.

    BAZ = range(0x100, 0x200, 4), Register32

48b4466abf m1n1.utils: Rewrite AddrLookup to improve performance & fix bugs 
* Fix correctness issues (ranges could end up overlapping)
* Split ranges instead of merging them on overlap (previously a single
  range overlapping everything would reduce the lookup to a linear
  search over all ranges)
* Support removal and generic mutations by splitting out a generic
  RangeMap class that can be used with arbitrary values/collections

d33d7ba89d kboot: Provide MAC addresses in device tree 
Read the MAC addresses from the ADT and store them in
"local-mac-address" properties on the relevant nodes in the FDT.
This relies on appropriate aliases in the provided FDT, which
matches how U-Boot provides MAC addresses on embedded targets.

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/.
