This is the mechanism in the HT code for - * supporting new Family or Model northbridges, as well as the means for supporting - * multiple northbridges in a single build or mixed revision northbridge sets. - * - * @par Adding a Method to the Northbridge - * - * To add a new method to the Northbridge, follow these steps. - * <ul> - * <li> Create a typedef for the Method with the correct parameters and return type. - * - * <ul> - * <li> Name the method typedef (F_METHOD_NAME)(), where METHOD_NAME is the same - * name as the method table item, but with "_"'s and UPPERCASE, rather than mixed case. - * @n <tt> typedef VOID (F_METHOD_NAME)(); </tt> @n - * - * <li> Make a reference type for references to a method implementation: - * @n <tt> /// Reference to a Method </tt> - * @n <tt> typedef F_METHOD_NAME *PF_METHOD_NAME </tt> @n - * </ul> - * - * <li> One of the parameters to @b all northbridge Methods is @b required to be a - * reference to its current northbridge object. By convention, this is the - * last parameter. - * - * <li> Provide a standard doxygen function preamble for the Method typedef. Begin the - * detailed description by providing a reference to the method instances page by including - * the lines below: - * @code - * * - * * @HtNbInstances - * * - * @endcode - * @note It is important to provide documentation for the method type, because the method may not - * have an implementation in any families supported by the current package. @n - * - * <li> Add to the ::NORTHBRIDGE struct an item for the Method: - * @n <tt> PF_METHOD_NAME MethodName; ///< Method: description. </tt> @n - * </ul> - * - * @par Implementing an Instance of a Northbridge method. - * - * To implement an instance of a method for a specific feature follow these steps. - * - * - In appropriate files, implement the method with the return type and parameters - * matching the Method typedef. - * - If the Method implementation is common to all families, use the northbridge file - * for the function area, for example, add a new coherent initialization support method to the - * coherent northbridge file. - * - If the Method implementation is unique to each supported northbridge, use the - * family specific file for that function area (create it, if it doesn't already exist). - * The family specific files have the same name as the common one suffixed with "FamNN", - * or "FamNNRevX" if for a model or revision. - * - * - Name the function MethodName(). If Family specific, FamNNMethodName(). - * - * - Create a doxygen function preamble for the method instance. Begin the detailed description with - * an Implements command to reference the method type and add this instance to the Method Instances page. - * @code - * * - * * @HtNbMethod{::F_METHOD_NAME}. - * * - * @endcode - * - * - To access other northbridge routines or data as part of the method implementation, - * the function must use Nb->OtherMethod(). Do not directly access other northbridge - * routines, because in the table there may be overrides or this routine may be shared by - * multiple configurations. - * - * - Add the instance, or the correct family specific instance, to the ::NORTHBRIDGE instances - * used by the northbridge constructor. - * - * - If a northbridge does not need an instance of the method use one of the CommonReturns from - * CommonReturns.h with the same return type. - * - * @par Making common Northbridge Methods. - * - * In some cases, Northbridge methods can easily have a common implementation because the hardware - * is very compatible or is even standard. In other cases, where processor family northbridges - * differ in their implementation, it may be possible to provide a single, common method - * implementation. This can be accomplished by adding Northbridge data members. - * - * For example, a bit position or bit field mask can be used to accommodate different bit placement or size. - * Another example, a small table can be used to translate index values from a common set - * to specific sets. - * - * The Northbridge Method Instance must use its NORTHBRIDGE reference parameter to access - * private data members. - * - * @par Invoking HT Northbridge Methods. - * - * Each unique northbridge is constructed based on matching the current northbridge. - * @n @code - * NORTHBRIDGE Nb; - * // Create the BSP's northbridge. - * NewNorthBridge (0, State, &Nb); - * State->Nb = &Nb; - * @endcode - * - * The following example shows how to invoke a Northbridge method. - * @n @code - * State->Nb->MethodName (State->Nb); - * @endcode - * - */ - -/*---------------------------------------------------------------------------- - * Mixed (DEFINITIONS AND MACROS / TYPEDEFS, STRUCTURES, ENUMS) - * - *---------------------------------------------------------------------------- - */ - -/*----------------------------------------------------------------------------- - * DEFINITIONS AND MACROS - * - *----------------------------------------------------------------------------- - */ - -/** Use a macro to convert a Node number to a PCI device.
