  51 *
  52 * 1) PTYPE1 packages do not contain sub-packages.
  53 *
  54 * ACPI_PTYPE1_FIXED: Fixed length, 1 or 2 object types:
  55 *     object type
  56 *     count
  57 *     object type
  58 *     count
  59 *
  60 * ACPI_PTYPE1_VAR: Variable length:
  61 *    object type (Int/Buf/Ref)
  62 *
  63 * ACPI_PTYPE1_OPTION: Package has some required and some optional elements:
  64 *      Used for _PRW
  65 *
  66 *
  67 * 2) PTYPE2 packages contain a variable number of sub-packages. Each of the
  68 *    different types describe the contents of each of the sub-packages.
  69 *
  70 * ACPI_PTYPE2: Each subpackage contains 1 or 2 object types:
  71 *     object type
  72 *     count
  73 *     object type
  74 *     count
  75 *
  76 * ACPI_PTYPE2_COUNT: Each subpackage has a count as first element:
  77 *     object type
  78 *
  79 * ACPI_PTYPE2_PKG_COUNT: Count of subpackages at start, 1 or 2 object types:
  80 *     object type
  81 *     count
  82 *     object type
  83 *     count
  84 *
  85 * ACPI_PTYPE2_FIXED: Each subpackage is of fixed length:
  86 *      Used for _PRT
  87 *
  88 * ACPI_PTYPE2_MIN: Each subpackage has a variable but minimum length

 105 * Predefined method/object information table.

 107 * These are the names that can actually be evaluated via acpi_evaluate_object.
 108 * Not present in this table are the following:
 109 *
 110 *      1) Predefined/Reserved names that are never evaluated via acpi_evaluate_object:
 111 *          _Lxx and _Exx GPE methods
 112 *          _Qxx EC methods
 113 *          _T_x compiler temporary variables
 114 *
 115 *      2) Predefined names that never actually exist within the AML code:
 116 *          Predefined resource descriptor field names
 117 *
 118 *      3) Predefined names that are implemented within ACPICA:
 119 *          _OSI
 120 *
 121 *      4) Some predefined names that are not documented within the ACPI spec.
 122 *          _WDG, _WED
 123 *
 124 * The main entries in the table each contain the following items:
 125 *
 126 * Name                 - The ACPI reserved name
 127 * param_count          - Number of arguments to the method
 128 * expected_btypes      - Allowed type(s) for the return value.
 129 *                        0 means that no return value is expected.
 130 *
 131 * For methods that return packages, the next entry in the table contains
 132 * information about the expected structure of the package. This information
 133 * is saved here (rather than in a separate table) in order to minimize the
 134 * overall size of the stored data.
