drivers/pc80/tpm: add support for TPM emulator SwTPM 2.0 module
Add software TPM 2.0 emulator to tpm device probe list. SwTPM: https://github.com/stefanberger/swtpm Tested on qemu q35 with MAINBOARD_HAS_LPC_TPM and MAINBOARD_HAS_TPM2 set in qemu-q35 Kconfig. Qemu: see qemu flags at https://s3hh.wordpress.com/2018/06/03/tpm-2-0-in-qemu/ How to see it work. Ubuntu 18.04: 1. Install SwTPM from https://github.com/stefanberger/swtpm 2. Add MAINBOARD_HAS_LPC_TPM and MAINBOARD_HAS_TPM2 to src/mainboard/emulation/qemu-q35/Kconfig and rebuild coreboot.rom 3. mkdir -p swtpm0 4. swtpm socket --tpmstate dir=swtpm0 --tpm2 --ctrl \ type=unixio,path=swtpm0/swtpm-sock --log level=20 & 5. qemu-system-x86_64 -machine q35 -m 2G \ -chardev socket,id=chrtpm,path=swtpm0/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm -device \ tpm-tis,tpmdev=tpm0 -pflash build/coreboot.rom \ -serial $(tty) -display none 6. Check boot log and search 'Found TPM'.
