Support for TPM command line options
Add TPM (frontend) hardware interface (TPM TIS) to Qemu
Add a debug register
Build the TPM
This patch uses the possibility to add a vendor-specific register and
adds a debug register useful for dumping the TIS's internal state. This
register is only active in a debug build (#define DEBUG_TIS).

testing there is a fairly extensive test suite as part of the SeaBIOS patches
since from within the BIOS one can have full access to all the TPM's registers.

What is the status of QEMU's transition from HMP to the QMP interface?
My current understanding is that QEMU provides new HMP commands for
humans, but HMP is being phased out as an API. Management tools
should rely only on QMP for new commands.

Because I instantiated it still with isa_create_simple(). This is going
to change in v5.
Thanks.

Kevin,
the above line
The following series of patches adds a TPM (Trusted Platform Module)
TIS (TPM Interface Spec) interface to Qemu and with that provides
means to access a backend implementing the actual TPM functionality.
This frontend enables for example Linux's TPM TIS (tpm_tis) driver.
I am also posting the

An alternative would be to measure the files in Qemu and make the measurements
available to SeaBIOS. This would introduce a dependency of Qemu on a sha1
