* USB: musb: workaround Blackfin FIFO anomaliesBryan Wu2009-12-231-2/+0
| | | | | | | | | | | | | | Some of these workarounds are already in place, but labeled as affecting all BF52x parts. Since we have official anomaly numbers now, use those defines. And since writing to the FIFO has a similar hang issue as reading from the FIFO, implement the workaround there too when necessary.

| | | | | | | | | | | Since we can't work around anomaly 05000380, throw a build error up and instruct the user to use a different mode.
