OMAP4: enable double linefill on 4460
Don't do that. We found a new errata around this recently which demanded to disable the DLF. Signature of the failure is full cache line getting corrupted. The errata should soon go into the ARM documentation. So this one too isn't useful even though it improves benchmarks.
Do you have an erratum number for this?
This was very recent BUG and not yet made it to the public errata numbers. Most likely next PL310 errata update should have this one documented.
Do you have _any_ identifier for it?
