Currently, it does not support the CRYPT command. Instead, it only sends an interrupt to notify the firmware that the crypt command has completed. It is a temporary workaround to resolve the boot issue in the Crypto Manager Self Test. Introduce a new "use_crypt_workaround" class attribute and set it to true in the AST2700 HACE model to enable this workaround by default for AST2700.
