Yifan Liu 00631f113f dm: TPM2 passthrough for post-launched VM with eventlog support
This patch enables TPM2 passthrough to post-launched VM with eventlog
support.
User starts by providing command line "--acpidev_pt <TPM2_HID>",
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.

v4 -> v5:
move tpm2 related logic from acpi.c to tpm.c
multiple API rename

Li Fei1 8ef2eedba4 dm: mitigate reset attack
When a platform reboots or shuts down, the contents of RAM are not immediately
lost but begins to decay. During this period, there is a short timeframe during
which an attacker can turn the platform back on to boot into a program that
dumps the contents of memory (e.g., cold boot attacks). Encryption keys and
other secrets can be easily compromised through this method.

We already erasing the guest memory data when the guest is shut down normally.
However, if the guest is shut down abnormally, the contents of RAM may still
there. This patch mitigate this kind reset attack for a DM launched VM by
erasing the guest memory data by the guest has been created.

Shuo A Liu a65e01ae95 dm: Reset virtio device before release
With virtio polling mode enabled, a timer is running in the virtio
backend service. And the timer will also be triggered if its frondend
driver didn't do the device reset in shutdown. A freed virtio device
will be accessed in the polling timer handler.

Do the virtio reset() callback specifically to clear the polling timer
before the free.

Yonghua Huang ccf606bded dm: remove redundant null check in unregister_mem_init
return value 'err' of mmio_rb_lookup() being 0 ensures
  'entry' is not NULL, hence checking it before 'free(entry)'
  is unnecessary.
