[Qemu-ppc] [PATCH v2 0/2] 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:
#> swtpm socket --tpmstate dir=/tmp/mytpm1 \
--ctrl type=unixio,path=/tmp/mytpm1/ctrl.sock \
--log level=2
If TPM 2 is desired, add --tpm2 as parameter to the above
and use the latest tpm2-preview branches of libtpms and swtpm.
In another terminal start QEMU:
#> sudo ./ppc64-softmmu/qemu-system-ppc64 -m 1024 \
-monitor stdio -vnc :12 -vga std \
--chardev socket,id=chrtpm,path=/tmp/mytpm1/ctrl.sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm \
-device tpm-spapr,tpmdev=tpm0 \
-L /tmp -bios boot_rom.bin \

- swtpm: https://github.com/stefanberger/swtpm/wiki
Changes:
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
Regards,
Stefan
