This doesn't look consistent (aside from the TX4939IDE_REG8/16 issue)
-- mm_outsw_swap() calls cpu_to_le16() before writing 16-bit data but
this code doesn't. So, either one of those should be wrong...
Thanks, this code should be wrong. IDE_TFLAG_OUT_DATA is totally
untested...
Hum, not necessarily...
If the data register is BE, this should work correctly, if I don't
mistake (once you fix the data register's address).
