*
* 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.
