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

- 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.

This turns on the system level cache. The carveout unmapping also moves
here, and now it handles T8103/T6000 properly.

Minimal initialization of the PCIe hardware such that the tunable
can be applied such that they don't have to be passed along in
the devicetree.

Allows Python to handle hypervisor exceptions, and implements exception

There are at least two types in the ADT related to USB,
but there's a decent chance that there are even more
required for other devices:
* A simple tunable that applies to a whole device node
and all its MMIO ranges specified in the "reg" property.
This one seems to just be mask32.
* A slightly more complex tunable that applies to a single
MMIO range specified in the "reg" property. So far I've
only seen 32 bit masks but the format looks like it should
also support 8,16 and 64 bit masks.

Now uses the same devicetree source as the kernel, verbatim, with the
required subset of kernel dt includes.

Turns out we had a bunch of silly dependencies on libc headers that are
not included with freestanding compilers. Fix all this and change the
CFLAGS to exclude libc headers and only include the built-in compiler
path.
Add our own versions of assert.h, errno.h, limits.h, and move malloc.h
and string.h together into a new path used as -isystem, so these headers
can be included using #include <>.
Remove a bunch of other dependencies in third-party code.
Add a strnlen function.
Disable building the libfdt overlay code for now, as it needs a strtoul
implementation. We can throw that in if/when we decide to use overlays.
