[ The last few days were extra busy with pushing previously queued
IDE bits upstream but I'm back to reviewing the new stuff. ]
Thanks for splitting your patch on smaller chunks.

I would prefer to avoid exporting this information to host drivers
if possible (they shouldn't need to know about higher-layer decisions,
plus this change opens the door for various "creative" abuses).
In case of sc1200 host driver fixes (patches #2-3/3) it should be
possible to remove the need for the below patch and at the same time
simplify sc1200 code further (more details in review of patch #2/2).
