-/**
- * EIP97 is an integrated security subsystem to accelerate cryptographic
- * functions and protocols to offload the host processor.
- * Some important hardware modules are briefly introduced below:
- *
- * Host Interface Adapter(HIA) - the main interface between the host
- * system and the hardware subsystem. It is responsible for attaching
- * processing engine to the specific host bus interface and provides a
- * standardized software view for off loading tasks to the engine.
- *
- * Command Descriptor Ring Manager(CDR Manager) - keeps track of how many
- * CD the host has prepared in the CDR. It monitors the fill level of its
- * CD-FIFO and if there's sufficient space for the next block of descriptors,
- * then it fires off a DMA request to fetch a block of CDs.
- *
- * Data fetch engine(DFE) - It is responsible for parsing the CD and
- * setting up the required control and packet data DMA transfers from
- * system memory to the processing engine.
- *
- * Result Descriptor Ring Manager(RDR Manager) - same as CDR Manager,
- * but target is result descriptors, Moreover, it also handles the RD
- * updates under control of the DSE. For each packet data segment
- * processed, the DSE triggers the RDR Manager to write the updated RD.
- * If triggered to update, the RDR Manager sets up a DMA operation to
- * copy the RD from the DSE to the correct location in the RDR.
- *
- * Data Store Engine(DSE) - It is responsible for parsing the prepared RD
- * and setting up the required control and packet data DMA transfers from
- * the processing engine to system memory.
- *
- * Advanced Interrupt Controllers(AICs) - receive interrupt request signals
- * from various sources and combine them into one interrupt output.
- * The AICs are used by:
- * - One for the HIA global and processing engine interrupts.
- * - The others for the descriptor ring interrupts.
