Re: IDE_PCCARD vs IDE_DIRECT in mpc8xx?

There are THREE ways. You can also use  an  external  IDE  interface,
independend of the 8xx PCMCIA controller.

Steven Scholz [off-list ref] has posted  the  hardware
design to this list some time ago.

Who can tell me which one is better?

This depends on your requirements.

Using a PCCard adapter is nice if you want to  be  able  to  add  and
remove  the  drive;  using a direct interface requires no PCMCIA slot
and no PCCard adapter, so it's much cheaper for mass production.
