+ * Bootloader Messaging Interface (BMI)
+ *
+ * BMI is a very simple messaging interface used during initialization

+ * application entry PC.
+ *
+ * It is used to download an application to QCA988x, to provide
+ * patches to code that is already resident on QCA988x, and generally
+ * to examine and modify state. The Host has an opportunity to use
+ * BMI only once during bootup. Once the Host issues a BMI_DONE
+ * command, this opportunity ends.
+ *
+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0. BMI requests all begin with a command
+ * (see below for specific commands), and are followed by
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using AR8K Counter #4. As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).
+ *
+ * BMI handles all required Target-side cache flushing.

+ * A single CopyEngine (CE) comprises two "rings":
+ * a source ring
+ * a destination ring
+ *
+ * Each ring consists of a number of descriptors which specify
+ * an address, length, and meta-data.
+ *
+ * Typically, one side of the PCIe interconnect (Host or Target)
+ * controls one ring and the other side controls the other ring.
+ * The source side chooses when to initiate a transfer and it
+ * chooses what to send (buffer address, length). The destination
+ * side keeps a supply of "anonymous receive buffers" available and
+ * it handles incoming data as it arrives (when the destination
+ * recieves an interrupt).
+ *
+ * The sender may send a simple buffer (address/length) or it may
+ * send a small list of buffers. When a small list is sent, hardware
+ * "gathers" these and they end up in a single destination buffer
+ * with a single interrupt.
+ *
+ * There are several "contexts" managed by this layer -- more, it
+ * may seem -- than should be needed. These are provided mainly for
+ * maximum flexibility and especially to facilitate a simpler HIF
+ * implementation. There are per-CopyEngine recv, send, and watermark
+ * contexts. These are supplied by the caller when a recv, send,
+ * or watermark handler is established and they are echoed back to
+ * the caller when the respective callbacks are invoked. There is
+ * also a per-transfer context supplied by the caller when a buffer
+ * (or sendlist) is sent and when a buffer is enqueued for recv.
+ * These per-transfer contexts are echoed back to the caller when
+ * the buffer is sent/received.

+/*
+ * This file specifies the WMI interface for the Unified Software
+ * Architecture.
+ *
+ * It includes definitions of all the commands and events. Commands are
+ * messages from the host to the target. Events and Replies are messages
+ * from the target to the host.
+ *
+ * Ownership of correctness in regards to WMI commands belongs to the host
+ * driver and the target is not required to validate parameters for value,
+ * proper range, or any other checking.
+ *
+ * Guidelines for extending this interface are below.
+ *
+ * 1. Add new WMI commands ONLY within the specified range - 0x9000 - 0x9fff
+ *
+ * 2. Use ONLY u32 type for defining member variables within WMI
+ * command/event structures. Do not use u8, u16, bool or
+ * enum types within these structures.
+ *
+ * 3. DO NOT define bit fields within structures. Implement bit fields
+ * using masks if necessary. Do not use the programming language's bit
+ * field definition.
+ *
+ * 4. Define macros for encode/decode of u8, u16 fields within
+ * the u32 variables. Use these macros for set/get of these fields.
+ * Try to use this to optimize the structure without bloating it with
+ * u32 variables for every lower sized field.
+ *
+ * 5. Do not use PACK/UNPACK attributes for the structures as each member
+ * variable is already 4-byte aligned by virtue of being a u32
+ * type.
+ *
+ * 6. Comment each parameter part of the WMI command/event structure by
+ * using the 2 stars at the begining of C comment instead of one star to
+ * enable HTML document generation using Doxygen.
