Its purpose is to attest the trustworthiness of a device against a human using time-based one-time passwords (TOTP), facilitating the Trusted Platform Module (TPM) to bind the TOTP secret to the known trustworthy system state. In addition to the original tpmtotp, given the new capabilities of in-TPM hmac calculation, the tpm2-totp's secret HMAC keys do not have to be exported from the TPM to the CPU's RAM on boot anymore. https://github.com/tpm2-software/tpm2-totp comment "tpm2-totp needs a toolchain w/ dynamic library" depends on BR2_STATIC_LIBS depends on !BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_ARM
