The AM57xx GP EVM boards are built on top the AM57xx BeagleBoard-X15. The EVM extends the BeagleBoard by adding a touchscreen, some buttons, and a handful of peripheral extension slots. Being a plugin extension of an existing standalone board; we define the am57xx-evm as a composite-DTB of the base am57xx-beagle-x15 and a new am57xx-evm overlay.
