This series adds the capability to instantiate an MMIO TPM TIS in ARM virt.
The series was tested with the swtpm/libtpms emulator. Automatic guest LUKS volume unlocking (tpm2) was successful. EDK2 support is under development [3]. Thanks to Ard for supporting me when setting up the test environment.
