 ===== files-4.x =====
 Kernel specific device source. Primarily the location of device DTS files. You will need to add a new device dts here and reference in image/Makefile under DEVICE_DTS.
 ===== patches-4.x =====
 Kernel source additions. No changes for basic device additions.
 ===== Makefile =====
 Platform wide device definition and common package set. Generally does not require modification when adding additional platform devices.
