30//      ADDRESS SPACE SEGMENTATION
31//
32//      This file must be included in the system.cpp file,
33//      for harware configuration : It is used to build
34//      the SOCLIB_SEGMENT_TABLE.
35//
36//      This file is also used by the ldscript generator,
37//      for embedded software generation.
38//
39//      It gives the system integrator the garanty
40//      that hardware and software have the same
41//      description of the address space segmentation.
42//
43//      The segment names cannot be changed.
