This CL adds a "tpm" Cargo cfg to crosvm which enables a TPM device
backed by libtpm2 simulator.
Tested by running the following inside cros_sdk:
LIBRARY_PATH=~/src/minijail LD_LIBRARY_PATH=~/src/minijail \
cargo run --release \
--features tpm \
-- \
run \
-r rootfs.ext4 \
--seccomp-policy-dir seccomp/x86_64/ \
-p init=/bin/bash \
-p panic=-1 \
--disable-sandbox \
vmlinux.bin
with a Linux image built from CL:1387655.
The TPM self test completes successfully with the following output:
