This series adds support for connecting TPM devices to the RISC-V virt
board. This is similar to how it works for the ARM virt board.
This was tested by first creating an emulated TPM device:
swtpm socket --tpm2 -t -d --tpmstate dir=/tmp/tpm \
--ctrl type=unixio,path=swtpm-sock
Then launching QEMU with:
-chardev socket,id=chrtpm,path=swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm \
-device tpm-tis-device,tpmdev=tpm0
The TPM device can be seen in the memory tree and the generated device
tree.
