This code is gated behind the CHAINLOADING define. To build a
release-style m1n1 with chainloading for use with the installer
or kmutil, use:
make CHAINLOADING=1 RELEASE=1
To tell m1n1 to chainload another binary, use this var payload:
chainload=<ESP partition UUID>;<file path>
e.g.
chainload=a17b7e46-e950-bb4f-bc82-8ab1047a058e;m1n1/m1n1.bin
Closes: #154

We already have breakpoints and symbols, let's make our life easier
by also allowing to break on symbols.

- Hide console by default unless booting in verbose mode.
- In verbose mode, enable USB early and poll for connection before
launching payloads.
- Show console on fallback to proxy.

Do not forget to clear the L2C_ERR flags in silent mode also. This is
necessary for proper recovery.

Use register definitions where they are now available. Start from full
AUDIO_P reset and set NCO ourselves (instead of relying on iBoot
values).

Make sure we read any reports before we start submitting new
descriptors. Also put sleep in busy-wait loop and make speaker_amp.py
exit once EOF is reached.

Drop the 'polling console' code as there are now better ways to achieve
the same. (One can use USB_VUART for second proxy session, see 85ee2f24)

Fill in register definitions and extend the driver code to introduce
support for RX channels. This involves change of channel numbering.

For those of us who can't write assembly but still need to run code on
the other side.
>>> from m1n1.loadobjs import *
>>> lp = LinkedProgram(u)
>>> lp.debug_printf("hello from the other side (%d)\n", 42)
TTY> hello from the other side (42)
0x1f
>>> lp.load_obj("build/test.o")
>>> lp.test()
TTY> hello from loaded object
0x19
>>> lp.clear_objs()

This works around a wraparound issue when the virt base ends up causing
the ADT address to go negative, when on 12.1+ using a dummy virt base.

This should not be required but it looks like the 12.1 ANS2 firmware
complains when NVME_CC.EN is cleared before the IO queues have been
deleted.
