However, not all features - like backlight, CAN, etc. are needed in U-Boot. To reduce SPL footprint, as the TPC70 is the first board (from i.MX6Q family of SoCs) which uses only DM in SPL and U-Boot proper, only the necessary subset of [1] was added to U-Boot.

For example I need "clocks" property, which is defined for almost all nodes. This incurs some extra cost in terms of footprint. To reduce the SPL size (to which dtb file size contributes), I had to not include full DTS from Linux in U-Boot. I only used a subset of it (only _really_ necessary description to run U-Boot) to reduce size of SPL binary.
