In addition to being embedded into the EMAC controller, the CPDMA hardware block is used in TI's CPSW switch controller. Fortunately, the programming interface to this hardware block remains somewhat consistent across these devices.
This series contains a new reusable cpdma implementation, as well as corresponding changes to plug unto the current emac driver. This code has been very briefly tested on DM365. Performance and stability tests have not yet been run. Further, this code does not handle transmit/receive errors properly. In short, this code is still pretty raw, and is being posted here for some early feedback on the overall approach.
