This provides TPM 2.0 functionality through Microsoft's fTPM Trusted Application running in OP-TEE secure world, using eMMC RPMB as persistent storage. fTPM support in U-Boot provides the foundation for measured boot and disk encryption use cases. The ARM64 condition ensures these apply only to A53/A72 cores and the MMC condition ensures fTPM is enabled only on platforms with eMMC hardware support.
