/**
 * @page regtableimpl Register Table Implementation Guide
 *
 * This register table implementation is modular and extensible, so that support code as
 * well as table data can be family specific or built out if not needed, and new types
 * of table entries can be added with low overhead.  Because many aspects are now generic,
 * there can be common implementations for CPU revision and platform feature matching and for
 * finding and iterating tables.
 *
 * @par Adding a new table entry type.
 *
 * To add a new table entry type follow these steps.
 * <ul>
 * <li>  Add a member to the enum TABLE_ENTRY_TYPE which is a descriptive name of the entry's purpose
 *       or distinct characteristics.
 *
 * <li>  Create an entry data struct with the customized data needed.  For example, custom register designations,
 *       data and mask sizes, or feature comparisons.  Name your struct by adding "_" and upper-casing the enum name
 *       and adding "_TYPE_ENTRY_DATA" at the end.
 *
 * <li>  Add the entry data type as a member of the TABLE_ENTRY_DATA union.  Be aware of the size of your
 *       entry data struct; all table entries in all tables will share any size increase you introduce!
 *
 * <li>  If your data entry contains any member types except for UINT32, you can't use the generic first union member
 *       for the initializers that make up the actual tables (it's just UINT32's). The generic MSR entry is
 *       an example. Follow the steps below:
 *
 *       <ul>
 *       <li>  Make a union which has your entry data type as the first member.  Use TABLE_ENTRY_DATA as the
 *             second member.  Name this with your register followed by "_DATA_INITIALIZER".
 *
 *       <li>  Make a copy of TABLE_ENTRY_FIELDS, and rename it your register "_TYPE_ENTRY_INITIALIZER".  Rename
 *             the TABLE_ENTRY_DATA member of that struct to have the type you created in the previous step.
 *             This type can be used to declare an array of entries and make a register table in some family specific
 *             file.
 *       </ul>
 *
 * <li>  Add the descriptor that will link table entries of your data type to an implementation for it.
 *       <ul>
 *       <li>  Find the options file which instantiates the CPU_SPECIFIC_SERVICES for each logical model that will
 *             support the new entry type.
 *
 *       <li> From there find the instantiation of its TABLE_ENTRY_TYPE_DESCRIPTOR.  Add a descriptor to the
 *            to the list for your new type.  Provide the name of a function which will implement the
 *            entry data.  The function name should reflect that it implements the action for the entry type.
 *            The function must be an instance of F_DO_TABLE_ENTRY.
 *       </ul>
 *
 * <li>  Implement the function for your entry type data.  (If parts of it are family specific add methods to
 *       CPU_SPECIFIC_SERVICES for that and implement them for each family or model required.)  @n
 *       The definition of the function must conform to F_DO_TABLE_ENTRY.
 *       In the function preamble, include a cross reference to the entry enum:
 *       @code
 *       *
 *       * @TableEntryTypeMethod{::MyRegister}
 *       *
 *       @endcode
 *
 * </ul>
 *
 * @par  Adding a new Register Table
 *
 * To add a new register table for a logical CPU model follow the steps below.
 *
 * <ul>
 * <li>  Find the options file which instantiates the CPU_SPECIFIC_SERVICES for the logical model that
 *       should include the table.
 *
 * <li>  From there find the instantiation of its REGISTER_TABLE list. Add the name of the new register table.
 * </ul>

/**
 * These are the available types of table entries.

 * Each type corresponds to:
 * - a semantics for the type specific data, for example semantics for a Register value,
 * Data value, and Mask value.
 * - optionally, including a method for type specific matching criteria

 * All types share in common a method to match CPU Family and Model and a method to match
