This mimics how a typed object works, where 'if' and 'comment' are
always set, regardless of if they have a value set or not.
It is safe to do this because of the way that _tree_to_qlit processes
these values (using dict.get with a default of None), resulting in no
change of output from _tree_to_q
Optional[List] is clunky; an empty sequence can more elegantly convey
"no variants". By downgrading "List" to "Sequence", we can also accept
tuples; this is useful for the empty tuple specifically, which we may

Introduce a new notifier, machine_init_done_late, that is notified after

This patch series is to enable TDX support.
This needs corresponding KVM patch for TDX[] and more patches are needed
that addresses generic corner cases, e.g. ACPI related stuff, are needed.
So This patch series is RFC.
More emulated devices and their behavior needs to be adjusted as some

Not disabling the UART leads to QEMU overwriting the UART receive buffer with
the newest received byte. The rx_level variable is added to allow the use of
the existing OpenTitan driver libraries.

The following patch will introduce incompatible behavior of SMM.
Introduce a property to keep the old behavior for compatibility.
To enable smm compat, use "-global ICH9-LPC.smm-compat=on" or
"-global PIIX4.smm-compat=on"
