4.x kernel and LCD capes

Hello everybody,

why new kernels 4.x turn on LCD Capes few seconds later? I am testing debian (from 2016) console images.
In 3.8.x kernel penguin logo displayed instantly and kernel logging massages are displayed.
Where I can download patched (DTC 1.4.1-gXYZXYZXYZ) for compiling with 4.x kernels?
