This change adds support for generating the device descriptor that
corresponds to the UARTSerialBusV2() ACPI macro.
The resulting ACPI code for ACPI_UART_RAW_DEVICE(115200, 64) is:
UartSerialBusV2 (0x0001C200, DataBitsEight, StopBitsOne,
0x00, LittleEndian, ParityTypeNone, FlowControlNone,
0x0040, 0x0040, "\\_SB.PCI0.UAR2",
0x00, ResourceConsumer, , Exclusive)

There have been changes to the way device properties are supported
in Linux[1] and Windows[2] which add flexibilty:
- non-standard UUIDs can be used instead of only ACPI_DP_UUID
- support for multiple different packages within the _DSD that
associate different properties with unique UUIDs.
To handle this I extracted the part that does the write of UUID and
properties to a separate function and defined a new PACKAGE type
which has the custom UUID as a name and can be used the same way that
child properties are today.
For example a PCIe root port for a USB4 port has a standard property
indicating the USB4 reference, and then two custom properties which
are defined for different attributes.
Example code:
/* Create property table */
acpi_dp *dsd = acpi_dp_new_table("_DSD");
acpi_dp_add_reference(dsd, "usb4-port", usb4_path);
/* Add package for hotplug */
acpi_dp *pkg = acpi_dp_new_table("6211e2c0-58a3-4af3-90e1-927a4e0c55a4");
acpi_dp_add_integer(pkg, "HotPlugSupportInD3", 1);
acpi_dp_add_package(dsd, pkg);
/* Add package for external port info */
pkg = acpi_dp_new_table("efcc06cc-73ac-4bc3-bff0-76143807c389");
acpi_dp_add_integer(pkg, "ExternalFacingPort", 1);
acpi_dp_add_package(dsd, pkg);
/* Write all properties */
acpi_dp_write(dsd);
Resulting ACPI:
Scope (\_SB.PCI0.TRP0)
{
Name (_DSD, Package ()
{
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301")
Package ()
{
Package () { "usb4-port", \_SB.PCI0.TDM0.RHUB.PRTA }
},
ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"),
Package ()
{
Package () { "HotPlugSupportInD3", One }
},
ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"),
Package ()
{
Package () { "ExternalFacingPort", One },
}
})
}

Stefan thinks they don't add value.
Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)
The exceptions are for:
- crossgcc (patch file)
- gcov (imported from gcc)
- elf.h (imported from GNU's libc)
- nvramtool (more complicated header)
The removed lines are:
