Hi, The following patch series adds support for the TDMA engine built into Marvell's Kirkwood-based SoCs, and enhances mv_cesa.c in order to use it for speeding up crypto operations. Kirkwood hardware contains a security accelerator, which can control DMA as well as crypto engines. It allows for operation with minimal software intervenience, which the following patches implement: using a chain of DMA descriptors, data input, configuration, engine startup and data output repeat fully automatically until the whole input data has been handled. The point for this being RFC is backwards-compatibility: earlier hardware (Orion) ships a (slightly) different DMA engine (IDMA) along with the same crypto engine, so in fact mv_cesa.c is in use on these platforms, too. But since I don't possess hardware of this kind, I am not able to make this code IDMA-compatible. Also, due to the quite massive reorganisation of code flow, I don't really see how to make TDMA support optional in mv_cesa.c.
