8c9b9808fa dm: rename ssram source files
guest ssram will be virtualized based on tcc driver interface,
 instead of pass-thru native rtct, rename its source files to
 avoid confusing:

  - rename:
  rtct.c -> vssram.c
  rtct.h -> vssram.h

 - move rtct.c from platform/acpci/ to platform/
 - new directory 'vssram' to hold vssram source files.

7d0c05f3ff dm: Skip injecting _PPC and _PCT when _PSS is not constructed
This patch is to eliminate kernel error msgs:
'ACPI Error: AE_NOT_FOUND, Evaluating _PSS'

This is caused by missing of _PSS table in guest ACPI. It would
happen when pstate is not injected to the guest.

Kernel ACPI pstate driver first probes
_PPC(performance capabilites) and _PCT(performance control)
in ACPI. If they exist, then it loads the _PSS(performance state).
If _PPC/_PCT are presented while _PSS is missing, it prints
the error msg.

In acrn-dm, _PPC/_PCT are hard-coded to all vCPUs, while _PSS
are constructed with the pCPUs' pstate data. This is base on
assumption that all VMs can have pstate.

Now the pstate is given to VM only when the VM is not sharing
any CPU(and no RTVM is setup in the scenario).
When the VM doesn't have pstate, the hypercall will return px_cnt=0,
and the _PSS is not constructed. In this case, _PPC/PCT should not
be injected, too.

da0d24326e dm: replace UUID with vmname.
The UUID has several usages before:
1, For HV to identify the static VM configuration of post-launched VM.
2, Seed virtualization.
3, Slightly prevent launching malicous VM from SOS as lack of secure
boot.

The UUID is confused to user, user don't understand what it is. And user
don't know where to get/apply the UUID. The worst experience is user
can't launch any VMs w/o re-compile the hv. Everything needs to be
static decided in building phase.

Now we decide to remove UUID and split each usage. For 1st usage, use
vmname as the identifier of static VM configuration. For 2nd one, we
will use --vseed as the new parameter. For 3rd one, will pretect by
SOS's dm-verity.

This patch will remove the UUID parameter and support 1st&3rd usages
from DM part. For 2nd usage, another patch will be submitted later.

of which the <TPM2_HID> will be searched from /proc/iomem for TPM2 buffer
start address and size. Furthermore, If TPM2 eventlog is supported,
TPM2 eventlog information will be retrieved from sysfs TPM2 table and
passed-through as well.

hv is responsible to ensure PTM is always enabled on hw root port if
that root port is PTM root-capable.  If PTM root is not enabled already in physical
root port before guest launch, guest OS can only enable it in root port's virtual
config space and PTM may not function as desired so we would rather not
to allow user to enable PTM on pass-thru device in this case.
Also revisit a few comments to add assumption that acrn only support a
simple PTM hierarch emulation i.e., EP (ptm requestor) is directly connected
to root port (ptm root), or ptm requestor is rcie).

V4:
 - Change behavior from V3: When users tries to enable PTM while PTM root is not enabled on
physical root port, allow user to launch VM and pass thru the device
with no PTM support.
V3:
 - When users tries to enable PTM while PTM root is not enabled on
physical root port, allow user to launch VM and enable PTM in virtual
root port.  This is not going to enable PTM on physical root port.

df64877c50 dm: PTM: Check PTM root has more than one child
Add one more sanity check: If the root port has more than
	one child, we won't enable PTM on the guest.
	This is not necessarily an error.  We flag it as
	error just because we don't have this type of hw
	configuration at development time thus this configuration
	is not tested.

721c866d63 dm: PTM: Enable ptm on passthru device
If user sets enable_ptm option on passthru device, passthru device
	calls ptm_probe() to check and enable ptm on passthru device.  If error
	is found during sanity check, ptm will not be enabled in the guest
	and an error will be reported to user.  However, this doesn't
	prevent user from launching guest and passing through the device to the guest.
	If no error is found, PTM is enabled in the guest and the
	passthru device will connect to virtual root port (which acts as PTM
	root) instead of virtual host bridge.

7e93f31e2c dm: PTM: Add virtual root port to vm
If PTM can be enabled on passthru device, a virtual root port
	is added to vm to act as ptm root.  And the passthru device is
	connected to the virtual root port instead of the virtual host bridge.

d5d792aa96 dm: PTM: Check if hw supports ptm
This patch probes whether hw supports ptm.  It is used to check whether ptm
	can be enabled on the passthru pci device.  It checks whether passthru
	device support PTM requestor capability, then check whether its upstream
	root port support PTM root role.  Errors are reported to user if sanity
	check fails.
