[PATCH v4 0/6] hw/riscv: Add TPM support to the virt board

[Alistair Francis <alistair.francis@opensource.wdc.com>]

From: Alistair Francis <alistair.francis@wdc.com>

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.
