  58  * FUNCTION:    AcpiExDoDebugObject
  59  *
  60  * PARAMETERS:  SourceDesc          - Object to be output to "Debug Object"
  61  *              Level               - Indentation level (used for packages)
  62  *              Index               - Current package element, zero if not pkg
  63  *
  64  * RETURN:      None
  65  *
  66  * DESCRIPTION: Handles stores to the AML Debug Object. For example:
  67  *              Store(INT1, Debug)
  68  *
  69  * This function is not compiled if ACPI_NO_ERROR_MESSAGES is set.
  70  *
  71  * This function is only enabled if AcpiGbl_EnableAmlDebugObject is set, or
  72  * if ACPI_LV_DEBUG_OBJECT is set in the AcpiDbgLevel. Thus, in the normal
  73  * operational case, stores to the debug object are ignored but can be easily
  74  * enabled if necessary.
