In OMAPs, a few devices have a local IO MMU. Their basic structure is similar to an ARM MMU, but less featured. IVA & Camera have one each on 3430/2430, a 2420 has those before mentioned and + 3rd in its video accelerator. The usage in TI kernels has varied a bit. Some times they are just load and lock TLB's, for others table walking can be enabled. In all cases if a table walk miss happens it is fatal and the IP block device will have to be reset. Paul Mundt had done the linux-omap tree version used with dspgateway.
