00404e9bc3 afk: propagate failures in afk_epic_rx correctly 
If the co-processor crashes afk_epic_poll will always fail which results
in afk_epic_rx getting stuck in an infinite loop calling afk_epic_poll
again and again.
This happens with e.g. old/incompatible DCP firmware.
Make sure the m1n1 proxy still works in those cases by propagating the
error correctly.

a40840f13c proxy: Expose usb_iodev_vuart_setup 
Expose the usb_iodev_vuart_setup function in uartproxy. This opens
the secondary ACM pipe to new uses outside the hypervisor. E.g. it can
be set up as another stream for sending proxy requests.

Sample usage from proxyclient:

    p.usb_iodev_vuart_setup(p.iodev_whoami())
    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.

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.

7e5054548a hv_vm: Rename SPTE_SYNC_TRACE to SPTE_TRACE_UNBUF 
It's not really synchronous, it just flushes USB buffering.

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.

3e807d6686 dart: shutdown to bypass mode 
This allows payloads to use DMA for anything that's not PCIe
even without a DART driver. It also restores the DART registers
the state the were left by iBoot.

d61bf13cb0 hv: shadow perf monitor IRQ mode and state 
The development Mac OS kernel panics if the PMCR0 sysreg is in an
unexpected state. To avoid that the hypervisor needs to shadow the
interrupt mode and interrupt active flag after it mask the PM FIQ.
Mac OS reads and writes frequently from PMCR0 and PMC 0/1 so handling
in m1n1 is preferred over Python.
