The remoteproc driver in mainline includes support for OMAP3/DM3730 (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/remoteproc/omap_remoteproc.c). We'd just need to choose an image with this built into the kernel.
Seems we could try to back-port the OpenCL support on BeagleBoard-X15 to BeagleBoard-xM and that'd be really helpful. See http://www.elinux.org/Beagleboard:BeagleBoard-X15#Will_I_be_able_to_program_the_C66x_DSPs.3F. It seems that currently the OpenCL integration into OpenCV requires use of different data types to address memory allocation challenges. See http://docs.opencv.org/2.4.3/modules/ocl/doc/introduction.html. I'm not sure if that'd be managable for you. There was also this project: http://beagleboard.org/project/opencv+acceleration/ (You can find projects on on OpenCV via http://beagleboard.org/project/?search=opencv. It'd be great to get people to register more of their projects, though I'm considering trying to work with hackster.io or hackaday.io to make a better project registry tool.)
