To be honest, the main point here is to make Russell happy. ;-) This is the second time he brought EBSA110 issue while talking about conversion of ARM platforms to use libata PATA so I've finally decided to do the patch just to have a reference example of how to deal with this and similar devices in a proper way. Even though the patch can't be tested EBSA110 is still a supported ARM platform and the patch should work fine in theory (+ it cannot break anything). OTOH it adds an extra code which has some cost from the long-term maintenance POV. Anyway, it is up to you to decide what to do with it. :-) Best regards, -- Bartlomiej Zolnierkiewicz Samsung R&D Institute Poland Samsung Electronics -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
