+ * target field in units of the granularity of the index_field
+ *
+ * Previously, the value was calculated as an index in terms of the
+ * width of the Data register, as below:
+ *
+ * obj_desc->index_field.Value = (u32)
+ * (Info->field_bit_position / ACPI_MUL_8 (
+ * obj_desc->Field.access_byte_width));
+ *
+ * February 2006: Tried value as a byte offset:
+ * obj_desc->index_field.Value = (u32)
+ * ACPI_DIV_8 (Info->field_bit_position);
