ister state cannot be manipulated directly by
setting the VM's memory, hence boot code is provided at the TD's reset
vector. This boot code takes boot parameters loaded in the TD's memory
and sets up the TD for the selftest.

The test reads CPUID values from inside a TD VM and compare them
to expected values.
The test targets CPUID values which are virtualized as "As Configured",
"As Configured (if Native)", "Calculated", "Fixed" and "Native"
according to the TD
The test calls get_td_vmcall_info from the guest and verifies the
expected returned values.
