SE mode now has a port that goes to whatever toplevel mem object the
CPU sees that does the appropriate translation for syscall emulation
SConscript:
translating port is a syscall emu only source
arch/alpha/system.cc:
base/loader/object_file.cc:
base/loader/object_file.hh:
Use the new functional port to write the binaries into memory
cpu/cpu_exec_context.cc:
cpu/cpu_exec_context.hh:
cpu/simple/cpu.cc:
We aren't always going to be writing straight to memory with syscalls
support writing to a cache
mem/port.hh:
Add a simple unidirectional functional port that panics on any incoming requests
mem/translating_port.hh:
make translating port inherit from the simple port
sim/system.cc:
sim/system.hh:
Add a functional port that is used to load the original binaries
