The ppi command line option for the TIS device on sysbus never worked
and caused an immediate segfault. Remove support for it since it also
needs support in the firmware and needs testing inside the VM.

We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.
Mechanical change doing:
$ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss)

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 \

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.

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.

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.

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.

Replace the global variables with inlined helper functions. getpagesize() is very

Some trace points are attributed to the wrong source file. Happens

Clean up with help of scripts/cleanup-trace-events.pl. Funnies
requiring manual post-processing:
* accel/tcg/cputlb.c trace points are in trace-events.
* block.c and blockdev.c trace points are in block/trace-events.
* hw/block/nvme.c uses the preprocessor to hide its trace point use
from cleanup-trace-events.pl.
* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

TPM subsytem is split into backends (see commit f4ede81eed2)
and frontends (see i.e. 3676bc69b35). Keep the emulated
hardware 'frontends' under hw/tpm/, but move the backends
in the backends/tpm/ directory.

We are going to split the TPM backends from the TPM emulated
hardware in the next commit. Make the TPM util helpers accessible
by moving local "tpm_util.h" to global "sysemu/tpm_util.h".

We are going to make "tpm_util.h" publicly accessible by
moving it to the include/ directory in the next commit.
The DEFINE_PROP_TPMBE() macro is only meaningful for the
TPM hardware files (in hw/tpm/), so keep this macro in a
local header.

The trace_event_get_state_backends() call is useful to avoid
making extensive calls (usually preparing arguments passed to
the tracing framework. In this case, the extensive work is
done in tpm_util_show_buffer(), and the arguments used to
call it don't involve extra processing. Simplify by moving
the TRACE_TPM_UTIL_SHOW_BUFFER check to tpm_util_show_buffer.

Clean up wrong usage of FALSE and TRUE in places that use "bool" from stdbool.h.
FALSE and TRUE (with capital letters) are the constants defined by glib for
being used with the "gboolean" type of glib. But some parts of the code also use
TRUE and FALSE for variables that are declared as "bool" (the type from <stdbool.h>).

As we plan to introduce a SysBus TPM TIS device, let's
make the TPMState a common struct usable by both the
ISADevice and the SysBusDevice. TPMStateISA embeds the
struct and inherits from the ISADevice.
The prototype of functions bound to be used by both
the ISA and SysBus devices is changed to take TPMState
handle.
A bunch of structs also are renamed to be specialized
for the ISA device. Besides those transformations, no
functional change is expected.
