initramfs.

f8110dd409 hv_exc: Handle M1RACLES mitigation here due to 12.0 spam 
macOS 12.0 added a silly ineffective "mitigation" that clears the
register on every context switch. This doesn't actually mitigate
anything, but it does make this sysreg trap performance-critical,
so we have to move its handling into the C side.

the firmware image by appending it to the initramfs.

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.

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.
