To support firmware secure boot, read secure information from efuse to know if current hardware module can support secure boot with certain cryptography method. This information should be prepared before downloading firmware, so read efuse right after power on at probe stage. The secure information includes secure cryptography method and secure key index that are used to choose proper key material when downloading firmware.
