Commit 49554856f0 fixed a problem, where TPM devices were not appearing
in the FDT, by delaying the FDT creation up until virt_machine_done().
This create a side effect (see gitlab #1925) - devices that need access
to the '/chosen' FDT node during realize() stopped working because, at
that point, we don't have a FDT.
This happens because our FDT creation is monolithic, but it doesn't need
to be. We can add the needed FDT components for realize() time and, at
the same time, do another FDT round where we account for dynamic sysbus
devices. In other words, the problem fixed by 49554856f0 could also be
fixed by postponing only create_fdt_sockets() and its dependencies,
leaving everything else from create_fdt() to be done during init().
Split the FDT creation in two parts:
- create_fdt(), now moved back to virt_machine_init(), will create FDT
nodes that doesn't depend on additional (dynamic) devices from the
sysbus;
- a new finalize_fdt() step is added, where create_fdt_sockets() and
friends is executed, accounting for the dynamic sysbus devices that
were added during realize().
This will make both use cases happy: TPM devices are still working as
intended, and devices such as 'guest-loader' have a FDT to work on
during realize().

Allow the VIA IDE controller to switch between both legacy and native modes by
calling pci_ide_update_mode() to reconfigure the device whenever PCI_CLASS_PROG
is updated.
This patch moves the initial setting of PCI_CLASS_PROG from via_ide_realize() to
via_ide_reset(), and removes the direct setting of PCI_INTERRUPT_PIN during PCI
bus reset since this is now managed by pci_ide_update_mode(). This ensures that
the device configuration is always consistent with respect to the currently
selected mode.

The via-ide device currently attempts to set the default BAR addresses to the
values shown in the datasheet, but this doesn't work for 2 reasons: firstly
BARS 1-4 do not set the bottom 2 bits to PCI_BASE_ADDRESS_SPACE_IO, and
secondly the initial PCI bus reset clears the values of all PCI device BARs
after the device itself has been reset.
Remove the setting of the default BAR addresses from via_ide_reset() to ensure
there is no doubt that these values are never exposed to the guest.

This function reads the value of the PCI_CLASS_PROG register for PCI IDE
controllers and configures the PCI BARs and/or IDE ioports accordingly.
In the case where we switch to legacy mode, the PCI BARs are set to return zero
(as suggested in the "PCI IDE Controller" specification), the legacy IDE ioports
are enabled, and the PCI interrupt pin cleared to indicate legacy IRQ routing.
Conversely when we switch to native mode, the legacy IDE ioports are disabled
and the PCI interrupt pin set to indicate native IRQ routing. The contents of
the PCI BARs are unspecified, but this is not an issue since if a PCI IDE
controller has been switched to native mode then its BARs will need to be
programmed.

Legacy software contains a standard mechanism for generating a reset to a
Serial ATA device - setting the SRST (software reset) bit in the Device
Control register.
Serial ATA has a more robust mechanism called COMRESET, also referred to
as port reset. A port reset is the preferred mechanism for error
recovery and should be used in place of software reset.
Commit e2a5d9b3d9 ("hw/ide/ahci: simplify and document PxCI handling")
improved the handling of PxCI, such that PxCI gets cleared after handling
a non-NCQ, or NCQ command (instead of incorrectly clearing PxCI after
receiving anything - even a FIS that failed to parse, which should NOT
clear PxCI, so that you can see which command slot that caused an error).
However, simply clearing PxCI after a non-NCQ, or NCQ command, is not
enough, we also need to clear PxCI when receiving a SRST in the Device
Control register.
A legacy software reset is performed by the host sending two H2D FISes,
the first H2D FIS asserts SRST, and the second H2D FIS deasserts SRST.
The first H2D FIS will not get a D2H reply, and requires the FIS to have
the C bit set to one, such that the HBA itself will clear the bit in PxCI.
The second H2D FIS will get a D2H reply once the diagnostic is completed.
The clearing of the bit in PxCI for this command should ideally be done
in ahci_init_d2h() (if it was a legacy software reset that caused the
reset (a COMRESET does not use a command slot)). However, since the reset
value for PxCI is 0, modify ahci_reset_port() to actually clear PxCI to 0,
that way we can avoid complex logic in ahci_init_d2h().
This fixes an issue for FreeBSD where the device would fail to reset.
The problem was not noticed in Linux, because Linux uses a COMRESET
instead of a legacy software reset by default.

The ICC_PMR_ELx and ICV_PMR_ELx bit masks returned from
ic{c,v}_fullprio_mask should technically also remove any
bit above 7 as these are marked reserved (read 0) and should
therefore should not be written as anything other than 0.
This was noted during a run of a proprietary test system and
discused on the mailing list [1] and initially thought not to
be an issue due to RES0 being technically allowed to be
written to and read back as long as the implementation does
not use the RES0 bits. It is very possible that the values
are used in comparison without masking, as pointed out by
Peter in [2], if (cs->hppi.prio >= cs->icc_pmr_el1) may well
do the wrong thing.
Masking these values in ic{c,v}_fullprio_mask() should fix
this and prevent any future problems with playing with the
values.
