fabe27e3f1 memory: Remap some carveouts as uncached 
This fixes display DART real-time cache hits causing AMCC exceptions.

The relevant carve-outs have flags 0x60004016; 0x60004002 is used for
DCP which is non-realtime, so I'm guessing the '16' means we should map
it uncached.

4575b35479 rust: Initial Rust-based EFI FAT32 chainloader 
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

Sample usage from proxyclient:

    p.iodev_set_usage(IODEV.USB_VUART, USAGE.UARTPROXY)
    # the second virtual serial now also serves proxy

b15be6bcd7 Remove hardcoded UART/WDT addresses 
The M1 Pro/Max Macs use a different base address for the UART and the
WDT than earlier models.

Remove hardcoded base addresses constants and replace them with loads
from the ADT.

- The base address of the WDT is already retrieved in wdt_disable; also
use this address when triggering a reboot.
- Retrieve the base address of uart0 in uart_init. If the operation
fails, the error will be signaled on the early uart (if not disabled).
- The early debug UART can’t use the ADT (or shouldn’t) so it is now
disabled by default. To enable it, add
-DEARLY_UART -DEARLY_UART_BASE=0xuart_address
to the CFLAGS.

da024ffbd8 memory: Only map available RAM 
We saw some crazy speculation running in the HV breaking things by
reading from invalid RAM, so let's actually map only what's available.
For now we do map all lowmem as we haven't seen SErrors there yet, but
we stop at the high boundary.

Fixes: #97
