++/*
++ * This file defines five types of data structures: singly-linked lists,
++ * lists, simple queues, tail queues, and circular queues.
++ *
++ *
++ * A singly-linked list is headed by a single forward pointer. The elements
++ * are singly linked for minimum space and pointer manipulation overhead at
++ * the expense of O(n) removal for arbitrary elements. New elements can be
++ * added to the list after an existing element or at the head of the list.
++ * Elements being removed from the head of the list should use the explicit
++ * macro for this purpose for optimum efficiency. A singly-linked list may
++ * only be traversed in the forward direction. Singly-linked lists are ideal
++ * for applications with large datasets and few or no removals or for
++ * implementing a LIFO queue.
++ *
++ * A list is headed by a single forward pointer (or an array of forward
++ * pointers for a hash table header). The elements are doubly linked
++ * so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before
++ * or after an existing element or at the head of the list. A list
++ * may only be traversed in the forward direction.
++ *
++ * A simple queue is headed by a pair of pointers, one the head of the
++ * list and the other to the tail of the list. The elements are singly
++ * linked to save space, so elements can only be removed from the
++ * head of the list. New elements can be added to the list before or after
++ * an existing element, at the head of the list, or at the end of the
++ * list. A simple queue may only be traversed in the forward direction.
++ *
++ * A tail queue is headed by a pair of pointers, one to the head of the
++ * list and the other to the tail of the list. The elements are doubly
++ * linked so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before or
++ * after an existing element, at the head of the list, or at the end of
++ * the list. A tail queue may be traversed in either direction.
++ *
++ * A circle queue is headed by a pair of pointers, one to the head of the
++ * list and the other to the tail of the list. The elements are doubly
++ * linked so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before or after
++ * an existing element, at the head of the list, or at the end of the list.
++ * A circle queue may be traversed in either direction, but has a more
++ * complex end of list detection.
++ *
++ * For details on the use of these macros, see the queue(3) manual page.

++/** @file
++ *
++ * A simple implementation of the Observer pattern. Any "module" can
++ * register as an observer or notifier. The notion of "module" is abstract and
++ * can mean anything used to identify either an observer or notifier. Usually
++ * it will be a pointer to a data structure which contains some state, ie an
++ * object.
++ *
++ * Before any notifiers can be added, the global notification manager must be
++ * brought up with dwc_alloc_notification_manager().
++ * dwc_free_notification_manager() will bring it down and free all resources.
++ * These would typically be called upon module load and unload. The
++ * notification manager is a single global instance that handles all registered
++ * observable modules and observers so this should be done only once.
++ *
++ * A module can be observable by using Notifications to publicize some general
++ * information about it's state or operation. It does not care who listens, or
++ * even if anyone listens, or what they do with the information. The observable
++ * modules do not need to know any information about it's observers or their
++ * interface, or their state or data.
++ *
++ * Any module can register to emit Notifications. It should publish a list of
++ * notifications that it can emit and their behavior, such as when they will get
++ * triggered, and what information will be provided to the observer. Then it
++ * should register itself as an observable module. See dwc_register_notifier().
++ *
++ * Any module can observe any observable, registered module, provided it has a
++ * handle to the other module and knows what notifications to observe. See
++ * dwc_add_observer().
++ *
++ * A function of type dwc_notifier_callback_t is called whenever a notification
++ * is triggered with one or more observers observing it. This function is
++ * called in it's own process so it may sleep or block if needed. It is
++ * guaranteed to be called sometime after the notification has occurred and will
++ * be called once per each time the notification is triggered. It will NOT be
++ * called in the same process context used to trigger the notification.
++ *
++ * @section Limitiations
++ *
++ * Keep in mind that Notifications that can be triggered in rapid sucession may
++ * schedule too many processes too handle. Be aware of this limitation when
++ * designing to use notifications, and only add notifications for appropriate
++ * observable information.
++ *
++ * Also Notification callbacks are not synchronous. If you need to synchronize
++ * the behavior between module/observer you must use other means. And perhaps
++ * that will mean Notifications are not the proper solution.

++/** @mainpage DWC Portability and Common Library
++ *
++ * This is the documentation for the DWC Portability and Common Library.
++ *
++ * @section intro Introduction
++ *
++ * The DWC Portability library consists of wrapper calls and data structures to
++ * all low-level functions which are typically provided by the OS. The WUDEV
++ * driver uses only these functions. In order to port the WUDEV driver, only
++ * the functions in this library need to be re-implemented, with the same
++ * behavior as documented here.
++ *
++ * The Common library consists of higher level functions, which rely only on
++ * calling the functions from the DWC Portability library. These common
++ * routines are shared across modules. Some of the common libraries need to be
++ * used directly by the driver programmer when porting WUDEV. Such as the
++ * parameter and notification libraries.
++ *
++ * @section low Portability Library OS Wrapper Functions
++ *
++ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that
++ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC(). All of
++ * these functions are included in the dwc_os.h file.
++ *
++ * There are many functions here covering a wide array of OS services. Please
++ * see dwc_os.h for details, and implementation notes for each function.
++ *
++ * @section common Common Library Functions
++ *
++ * Any function starting with dwc and in all lowercase is a common library
++ * routine. These functions have a portable implementation and do not need to
++ * be reimplemented when porting. The common routines can be used by any
++ * driver, and some must be used by the end user to control the drivers. For
++ * example, you must use the Parameter common library in order to set the
++ * parameters in the WUDEV module.
++ *
++ * The common libraries consist of the following:
++ *
++ * - Connection Contexts - Used internally and can be used by end-user. See dwc_cc.h
++ * - Parameters - Used internally and can be used by end-user. See dwc_params.h
++ * - Notifications - Used internally and can be used by end-user. See dwc_notifier.h
++ * - Lists - Used internally and can be used by end-user. See dwc_list.h
++ * - Memory Debugging - Used internally and can be used by end-user. See dwc_os.h
++ * - Modpow - Used internally only. See dwc_modpow.h
++ * - DH - Used internally only. See dwc_dh.h
++ * - Crypto - Used internally only. See dwc_crypto.h
++ *
++ *
++ * @section prereq Prerequistes For dwc_os.h
++ * @subsection types Data Types
++ *
++ * The dwc_os.h file assumes that several low-level data types are pre defined for the
++ * compilation environment. These data types are:
++ *
++ * - uint8_t - unsigned 8-bit data type
++ * - int8_t - signed 8-bit data type
++ * - uint16_t - unsigned 16-bit data type
++ * - int16_t - signed 16-bit data type
++ * - uint32_t - unsigned 32-bit data type
++ * - int32_t - signed 32-bit data type
++ * - uint64_t - unsigned 64-bit data type
++ * - int64_t - signed 64-bit data type
++ *
++ * Ensure that these are defined before using dwc_os.h. The easiest way to do
++ * that is to modify the top of the file to include the appropriate header.
++ * This is already done for the Linux environment. If the DWC_LINUX macro is
++ * defined, the correct header will be added. A standard header <stdint.h> is
++ * also used for environments where standard C headers are available.
++ *
++ * @subsection stdarg Variable Arguments
++ *
++ * Variable arguments are provided by a standard C header <stdarg.h>. it is
++ * available in Both the Linux and ANSI C enviornment. An equivalent must be
++ * provided in your enviornment in order to use dwc_os.h with the debug and
++ * tracing message functionality.
++ *
++ * @subsection thread Threading
++ *
++ * WUDEV Core must be run on an operating system that provides for multiple
++ * threads/processes. Threading can be implemented in many ways, even in
++ * embedded systems without an operating system. At the bare minimum, the
++ * system should be able to start any number of processes at any time to handle
++ * special work. It need not be a pre-emptive system. Process context can
++ * change upon a call to a blocking function. The hardware interrupt context
++ * that calls the module's ISR() function must be differentiable from process
++ * context, even if your processes are impemented via a hardware interrupt.
++ * Further locking mechanism between process must exist (or be implemented), and
++ * process context must have a way to disable interrupts for a period of time to
++ * lock them out. If all of this exists, the functions in dwc_os.h related to
++ * threading should be able to be implemented with the defined behavior.

++ *
++ * The CIL manages the memory map for the core so that the HCD and PCD
++ * don't have to do this separately. It also handles basic tasks like
++ * reading/writing the registers and data FIFOs in the controller.
++ * Some of the data access functions provide encapsulation of several
++ * operations required to perform a task, such as writing multiple
++ * registers to start a transfer. Finally, the CIL performs basic
++ * services that are not specific to either the host or device modes
++ * of operation. These services include management of the OTG Host
++ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
++ * Diagnostic API is also provided to allow testing of the controller
++ * hardware.
++ *
++ * The Core Interface Layer has the following requirements:
++ * - Provides basic controller operations.
++ * - Minimal use of OS services.
++ * - The OS services used will be abstracted by using inline functions
++ * or macros.

++ * The dwc_otg_driver module provides the initialization and cleanup entry
++ * points for the DWC_otg driver. This module will be dynamically installed
++ * after Linux is booted using the insmod command. When the module is
++ * installed, the dwc_otg_driver_init function is called. When the module is
++ * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
++ *
++ * This module also defines a data structure for the dwc_otg_driver, which is
++ * used in conjunction with the standard ARM lm_device structure. These
++ * structures allow the OTG driver to comply with the standard Linux driver
++ * model in which devices and drivers are registered with a bus driver. This
++ * has the benefit that Linux can expose attributes of the driver and device
++ * in its special sysfs file system. Users can then read or write files in
++ * this file system to perform diagnostics on the driver components or the
++ * device.

++ * This file contains the data structures for accessing the DWC_otg core registers.
++ *
++ * The application interfaces with the HS OTG core by reading from and
++ * writing to the Control and Status Register (CSR) space through the
++ * AHB Slave interface. These registers are 32 bits wide, and the
++ * addresses are 32-bit-block aligned.
++ * CSRs are classified as follows:
++ * - Core Global Registers
++ * - Device Mode Registers
++ * - Device Global Registers
++ * - Device Endpoint Specific Registers
++ * - Host Mode Registers
++ * - Host Global Registers
++ * - Host Port CSRs
++ * - Host Channel Specific Registers
++ *
++ * Only the Core Global registers can be accessed in both Device and
++ * Host modes. When the HS OTG core is operating in one mode, either
++ * Device or Host, the application must not access registers from the
++ * other mode. When the core switches from one mode to another, the
++ * registers in the new mode of operation must be reprogrammed as they
++ * would be after a power-on reset.
