You mean why is it desirable to turn it off? Right now there's a mess
of tidspbridge branches, some work, some don't, some have migrated to
iommu, some don't. In mainline all this, plus the status on dsp-link,
should be irrelevant, a configuration solves all the issues.

Once the iommu migration works (haven't managed to get it working
myself), and it has been merged into mainline, then we can think about
enabling it unconditionally. In the meantime, enabling unconditionally
would break the tidspbridge that is in staging (mainline).

Will do, after you reply the above.
