[PATCH] kill eth_io_copy_and_sum()
On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len). The function name is highly misguiding (it _never_ does any checksums), the last argument is just a noise and simply expanding the call to memcpy_fromio() gives shorter and more readable source. For a lot of reasons it has almost no remaining users, so it's better to just outright kill it.
