Lots of fixes to serialization and naming of various device
objects. The improper serialization of arrays was particularly bad. dev/alpha_console.cc: dev/isa_fake.cc: dev/ns_gige.cc: dev/pciconfigall.cc: dev/tsunami_cchip.cc: dev/tsunami_io.cc: dev/tsunami_pchip.cc: the pio interface is a different simobject and should have a different name. dev/ethertap.cc: fix serialization. dev/ide_ctrl.cc: - the pio interface is a different simobject and should have a different name. - properly initialize variables - When serializing an array, the size is the number of elements, not the number of bytes! dev/pcidev.cc: When serializing an array, the size is the number of elements, not the number of bytes! dev/tsunami_io.hh: Don't make objects SimObjects if they're not exposed to python. Don't add serialization functions to events, it's generally not what you want. allow the real time clock and interval timer to serialize themselves, must pass a base name since it is not a SimObject and the values will be going into the section of the parent. --HG-- extra : convert_revision : 3fc5de9b858ed770c8f385cf38b53242cf859c33
