+/**
+ * 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.
