Xen devel - Aug 2006 - [PATCH][vTPM][REPOST] 3/3: TPM device model for qemu dm (again)

Sorry, but previously posted patch had a call to xenstore_get_devices() instead
of
xenstore_domain_get_devices() in it and would not compile. This patch here fixes
the problem.

This patch adds a TPM device model to the qemu dm for fully virtualized
VMs. It is enabled in the VM only if the user requests a TPM device in
the vm configuration file using the ''vtpm=[...]'' line. It
enables the
qemu device model command line with a ''vtpm_instance <instance
number>''
parameter.
This patch also adds some fairly generic xenstore access functions to the
xenstore.c file.
I am using these functions to read vTPM specific configuration data.
