[PATCH v4 0/8] Add vTPM emulator supportfor ppc64 platform |

The following series of patches adds vTPM emulator support for the
ppc64 platform (pSeries).
It can be tested as follows with swtpm/libtpms:
mkdir /tmp/mytpm1
swtpm socket --tpmstate dir=/tmp/mytpm1 \
--ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock \
--log level=20
If TPM 2 is desired, add --tpm2 as parameter to the above.
In another terminal start QEMU:
sudo ./ppc64-softmmu/qemu-system-ppc64 -display sdl \
-machine pseries,accel=kvm \
-m 1024 -bios slof.bin -boot menu=on \
-nodefaults -device VGA -device pci-ohci -device usb-kbd \
-chardev socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm \
-device tpm-spapr,tpmdev=tpm0 \
-device spapr-vscsi,id=scsi0,reg=0x00002000 \
-device
virtio-blk-pci,scsi=off,bus=pci.0,addr=0x3,drive=drive-virtio-disk0,id=virtio-disk0
\
-drive file=test.img,format=raw,if=none,id=drive-virtio-disk0

Changes:
v3->v4:
- addressed comments to v3
- reworked suspend/resume support that requires extensions to backends
v2->v3:
- patch 1: a TPM 2 is identified by IBM,vtpm20 in the compatible node
- patch 1: convert to tracing to display Tx and Rx buffers
- added documentation patch
- added patch to enable TPM device as part of pSeries
v1->v2:
- followed Cedric Le Goater's suggestions to patch 1
- send appropriate CRQ error responses if DMA read or write fails
- renamed tpm_spapr_got_payload to tpm_spapr_process_cmd and
pass endianess-adjusted data pointer from CRQ to it

Stefan
