The last time someone (I think Akira Iguchi) wanted to add a new powerpc specific IDE driver, that was rejected based on the argument that drivers/ide/ is going away soon.

It's certainly not easy to support all ATA chips that have special capabilities and bugs, but the electra and the mpc8349-itx both seem to support only the most basic ATA PIO mode anyway, which does not require much special handling beyond finding the right mmio addresses.
