+ *
+ *
+ * Implicit data type conversion: string-to-integer
+ * --------------------------------------------------
+ *
+ * Base is always 16. This is the ACPI_STRTOUL_BASE16 case.
+ *
+ * Example:
+ *      Add ("BA98", Arg0, Local0)
+ *
+ * The integer is initialized to the value zero.
+ * The ASCII string is interpreted as a hexadecimal constant.
+ *
+ *  1)  A "0x" prefix is not allowed. However, ACPICA allows this for
+ *      compatibility with previous ACPICA. (NO ERROR)
+ *
+ *  2)  Terminates when the size of an integer is reached (32 or 64 bits).
+ *      (NO ERROR)
+ *
+ *  3)  The first non-hex character terminates the conversion without error.
+ *      (NO ERROR)
+ *
+ *  4)  Conversion of a null (zero-length) string to an integer is not
+ *      allowed. However, ACPICA allows this for compatibility with previous
+ *      ACPICA. This conversion returns the value 0. (NO ERROR)
+ *
+ *
+ * Explicit data type conversion:  to_integer() with string operand
+ * ---------------------------------------------------------------
+ *
+ * Base is either 10 (default) or 16 (with 0x prefix)
+ *
+ * Examples:
+ *      to_integer ("1000")
+ *      to_integer ("0xABCD")
+ *
+ *  1)  Can be (must be) either a decimal or hexadecimal numeric string.
+ *      A hex value must be prefixed by "0x" or it is interpreted as a decimal.
+ *
+ *  2)  The value must not exceed the maximum of an integer value. ACPI spec
+ *      states the behavior is "unpredictable", so ACPICA matches the behavior
+ *      of the implicit conversion case.(NO ERROR)
+ *
+ *  3)  Behavior on the first non-hex character is not specified by the ACPI
+ *      spec, so ACPICA matches the behavior of the implicit conversion case
+ *      and terminates. (NO ERROR)
+ *
+ *  4)  A null (zero-length) string is illegal.
+ *      However, ACPICA allows this for compatibility with previous ACPICA.
+ *      This conversion returns the value 0. (NO ERROR)

+ *              size in Flags (often the current mode of the interpreter).
+ *
+ * Values for Flags:
+ *      ACPI_STRTOUL_32BIT      - Max integer value is 32 bits
+ *      ACPI_STRTOUL_64BIT      - Max integer value is 64 bits
+ *      ACPI_STRTOUL_BASE16     - Input string is hexadecimal. Default
+ *                                is 10/16 based on string prefix (0x).
+ *
+ * NOTES:
+ *   Negative numbers are not supported, as they are not supported by ACPI.
+ *
+ *   Supports only base 16 or base 10 strings/values. Does not
+ *   support Octal strings, as these are not supported by ACPI.
+ *
+ * Current users of this support:
+ *
+ *  interpreter - Implicit and explicit conversions, GPE method names
+ *  debugger    - Command line input string conversion
+ *  iASL        - Main parser, conversion of constants to integers
+ *  iASL        - Data Table Compiler parser (constant math expressions)
+ *  iASL        - Preprocessor (constant math expressions)
+ *  acpi_dump   - Input table addresses
+ *  acpi_exec   - Testing of the acpi_ut_strtoul64 function
+ *
+ * Note concerning callers:
+ *   acpi_gbl_integer_byte_width can be used to set the 32/64 limit. If used,
+ *   this global should be set to the proper width. For the core ACPICA code,
+ *   this width depends on the DSDT version. For iASL, the default byte
+ *   width is always 8 for the parser, but error checking is performed later
+ *   to flag cases where a 64-bit constant is defined in a 32-bit DSDT/SSDT.
