Put a cell phone chip on a board with normal connectors. the problem is that we are now at a time when a lot of these systems on a chip need to have a lot of power management to run low power and to run cool. Most are not designed to just have all the silicon on all the time and run normally that way. With either a linux system or android system most will not run that way unless the vendors full bsp support for all portions of the system are released. I suspect they are turning on only the apps processors and maybe a few other assets and just leaving them on, rather than modifying drivers to turn them on as needed. To expose such in open source would expose a lot of tricks they don't want to share. The Pi processor is not such a system, but is representative of what you would see as a small portion of one of the ones you referenced. In fact I would not be surprised if in the case of the dongle like you describe which I found for the chip in my Galaxy Note 2 the Egynos 4412 has an arm7 equivalent of faster than the Pi completely held in reset and ignored. The modems frequently are on the systems and are hopefully left turned off and passive since there are no RF external gear to make them useful. thanks Jim
