 * ACPI_PTYPE1_FIXED: Fixed length, 1 or 2 object types:
 *      object type
 *      count
 *      object type
 *      count
 *
 * ACPI_PTYPE1_VAR: Variable length:
 *      object type (Int/Buf/Ref)
 *
 * ACPI_PTYPE1_OPTION: Package has some required and some optional elements
 *      (Used for _PRW)
 *
 *
 * 2) PTYPE2 packages contain a variable number of sub-packages. Each of the
 *    different types describe the contents of each of the sub-packages.
 *
 * ACPI_PTYPE2: Each subpackage contains 1 or 2 object types:
 *      object type
 *      count
 *      object type
 *      count
 *      (Used for _ALR,_MLS,_PSS,_TRT,_TSS)
 *
 * ACPI_PTYPE2_COUNT: Each subpackage has a count as first element:
 *      object type
 *      (Used for _CSD,_PSD,_TSD)
 *
 * ACPI_PTYPE2_PKG_COUNT: Count of subpackages at start, 1 or 2 object types:
 *      object type
 *      count
 *      object type
 *      count
 *      (Used for _CST)
 *
 * ACPI_PTYPE2_FIXED: Each subpackage is of fixed length

 * These are the names that can actually be evaluated via acpi_evaluate_object.

 *          _Lxx and _Exx GPE methods
 *          _Qxx EC methods
 *          _T_x compiler temporary variables
 *
 *      2) Predefined names that never actually exist within the AML code:
 *          Predefined resource descriptor field names
 *
 *      3) Predefined names that are implemented within ACPICA:
 *          _OSI
 *
 *      4) Some predefined names that are not documented within the ACPI spec.
 *          _WDG, _WED
 *
 * The main entries in the table each contain the following items:
 *
 * Name                 - The ACPI reserved name
 * param_count          - Number of arguments to the method
 * expected_btypes      - Allowed type(s) for the return value.
 *                        0 means that no return value is expected.
 *
 * For methods that return packages, the next entry in the table contains
 * information about the expected structure of the package. This information
 * is saved here (rather than in a separate table) in order to minimize the
 * overall size of the stored data.
