+ * String conversion rules as written in the ACPI specification. The error
+ * conditions and behavior are different depending on the type of conversion.
+ *
+ *
+ * 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)

+ *
+ * FUNCTION: acpi_ut_strtoul64
+ *
+ * PARAMETERS: string - Null terminated input string
+ * flags - Conversion info, see below
+ * return_value - Where the converted integer is
+ * returned
+ *
+ * RETURN: Status and Converted value
+ *
+ * DESCRIPTION: Convert a string into an unsigned value. Performs either a
+ * 32-bit or 64-bit conversion, depending on the input integer
+ * 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.
