I don't think this is a good idea - other OMAP chips including the recently introduced OMAP3630 and OMAP4 do not have this bug and would be unnecessarily hampered. Additionally, the issue on 3430 is limited to channels enabled in both directions at the same time. There is no restriction on multiple channels enabled in the same direction. There's a workaround based on this fact that Ajay and I developed. I'd like to post that instead.
The one that uses system dma ?? I didn't quite liked those. What we can do is check for cpu_is_omap3430() || cpu_is_omap2430() and only apply the workaround for that.
