This makes the dp-audio addresses visible. E.g. on t8103 on the sio node, look at the SAUD device in the dmashim list:

            dmashim = [Container: 
    name = u'SSPI' (total 4)
    base = 0x0000000235100000
    length = 0x0000000000100000
    unk1 = 0x0000000D
    unk2 = 0x0000000E
    unk3 = 0x0000000F
    stride = 0x00004000, Container: 
    name = u'SUAR' (total 4)
    base = 0x0000000235200000
    length = 0x0000000000100000
    unk1 = 0x00000001
    unk2 = 0x00000002
    unk3 = 0x00000003
    stride = 0x00004000, Container: 
    name = u'SAUD' (total 4)
    base = 0x0000000238300000
    length = 0x0000000000100000
    unk1 = 0x0000001E
    unk2 = 0x0000001F
    unk3 = 0x00000020
    stride = 0x00004000]

This breaks running macOS under the hypervisor. It panics with:

RTBuddy(AOP): Boot args override: wdt = -1
panic(cpu 0 caller 0xfffffe001687c650): "RTBuddy(AOP)::getSegmentMap " "OSArray *RTBuddy::getSegmentMap() const:2438: REQUIRE failed: iterator == nullptr" @RTBuddy.cpp:2438

That's weird.

This is change breaks the ADT parsing. On a freshly booted system

python3 -m m1n1.adt -r ref.adt
tools/chainload.py -r ../build/m1n1.bin
python3 -m m1n1.adt -r broken.adt

ref.adt and broken.adt differ and the second adt fetch throws following assertion:
