Routine Description:
The main startup routine for the NT Setup Loader. This is the entrypoint
called by the ARC firmware.
If successful, this routine will never return, it will start NT directly.
Arguments:
Argc - Supplies the number of arguments that were provided on the
command that invoked this program.
Argv - Supplies a pointer to a vector of pointers to null terminated
argument strings.
Envp - Supplies a pointer to a vector of pointers to null terminated
environment variables.
Return Value:
ARC_STATUS if unsuccessful.
