Ninad PalsuleandStefan Berger 139fdb3ed8 tpm: Add support for TPM device over I2C bus
Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices. I2C model only supports
TPM2 protocol.

This commit includes changes for the common code.
- Added I2C emulation model. Logic was added in the model to temporarily
  cache the data as I2C interface works per byte basis.
- New tpm type "tpm-tis-i2c" added for I2C support. The user has to
  provide this string on command line.

Testing:
  TPM I2C device module is tested using SWTPM (software based TPM
  package). Qemu uses the rainier machine and is connected to swtpm over
  the socket interface.

  The command to start swtpm is as follows:
  $ swtpm socket --tpmstate dir=/tmp/mytpm1    \
                 --ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock  \
                 --tpm2 --log level=100

  The command to start qemu is as follows:
  $ qemu-system-arm -M rainier-bmc -nographic \
            -kernel ${IMAGEPATH}/fitImage-linux.bin \
            -dtb ${IMAGEPATH}/aspeed-bmc-ibm-rainier.dtb \

Ninad PalsuleandStefan Berger bbadfb2e0a tpm: Extend common APIs to support TPM TIS I2C
Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices.

This commit includes changes for the common code.
- Added support for the new checksum registers which are required for
  the I2C support. The checksum calculation is handled in the qemu
  common code.
- Added wrapper function for read and write data so that I2C code can
  call it without MMIO interface.

The TPM TIS I2C spec describes in the table in section "Interface Locality
Usage per Register" that the TPM_INT_ENABLE and TPM_INT_STATUS registers
must be writable for any locality even if the locality is not the active
locality. Therefore, remove the checks whether the writing locality is the
active locality for these registers.

Ross LagerwallandStefan Berger f0ccce6a95 tpm_crb: Avoid backend startup just before shutdown under Xen
When running under Xen and the guest reboots, it boots into a new domain
with a new QEMU process (and a new swtpm process if using the emulator
backend). The existing reset function is triggered just before the old
QEMU process exists which causes QEMU to startup the TPM backend and
then immediately shut it down. This is probably harmless but when using
the emulated backend, it wastes CPU and IO time reloading state, etc.

Fix this by calling the reset function directly from realize() when
running under Xen. During a reboot, this will be called by the QEMU
process for the new domain.

Anthony PERARDandStefan Berger e37a0ef460 tpm_crb: mark command buffer as dirty on request completion
At the moment, there doesn't seems to be any way to know that QEMU
made modification to the command buffer. This is potentially an issue
on Xen while migrating a guest, as modification to the buffer after
the migration as started could be ignored and not transfered to the
destination.

Mark the memory region of the command buffer as dirty once a request
is completed.

Peter MaydellandStefan Berger 4d84bb6c8b hw/tpm/tpm_tis_common.c: Assert that locty is in range
In tpm_tis_mmio_read(), tpm_tis_mmio_write() and
tpm_tis_dump_state(), we calculate a locality index with
tpm_tis_locality_from_addr() and then use it as an index into the
s->loc[] array.  In all these cases, the array index can't overflow
because the MemoryRegion is sized to be TPM_TIS_NUM_LOCALITIES <<
TPM_TIS_LOCALITY_SHIFT bytes.  However, Coverity can't see that, and
it complains (CID 1487138, 1487180, 1487188, 1487198, 1487240).

Add an assertion to tpm_tis_locality_from_addr() that the calculated
locality index is valid, which will help Coverity and also catch any
potential future bug where the MemoryRegion isn't sized exactly.
