/*
* 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.
