Callers must pass ELF machine, byte swapping and symbol LSB clearing information to ELF loader. A.out loader needs page size information, pass that too as a parameter. Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw. Adjust callers. Also use target_phys_addr_t instead of target_ulong for addresses: loader addresses aren't virtual.
