+ * Structure describing a run-time NFP symbol.
+ *
+ * The memory target of the symbol is generally the CPP target number and can be
+ * used directly by the nfp_cpp API calls.  However, in some cases (i.e., for
+ * local memory or control store) the target is encoded using a negative number.
+ *
+ * When the target type can not be used to fully describe the location of a
+ * symbol the domain field is used to further specify the location (i.e., the
+ * specific ME or island number).
+ *
+ * For ME target resources, 'domain' is an MEID.
+ * For Island target resources, 'domain' is an island ID, with the one exception
+ * of "sram" symbols for backward compatibility, which are viewed as global.
