A module parameter is not necessarily the best/only option.
ahci_platform already has infrastructure set up to deal with
platform-specific quirks.  An internal flag seems more appropriate
to enable automatic handling of this on the specific platforms where
it applies (plus the revert Tejun has already mentioned).

The problem is that there's no way to identify the controller in
question, so we can't do this automatically, so might just as well do
it in the simplest way for now.  :(

Well, a module parameter is no good,
because that method would affect all attached controllers
rather than just the one(s) with the issue.

Something in sysfs perhaps.

See the method already described in my previous message.
grep for IMX53_AHCI.
