It looks like MUSB with CPPI DMA, similar to what is in other Davinci chips. If so, there's a kernel driver for it in Linux (see drivers/usb/musb/) with support for the DMA engine as well. OMAP3 uses MUSB with its own "Inventra" DMA engine. - Anand _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
