How to implement device tree within layer in latest STM32MP15 ecosystem release

[Guilam]

Hello,
Would it be possible to have an updated guide on how to use a custom device tree within my own layer for latest STM32MP1 Ecosystem ?
The one provided here  "How to compile the device tree with the Distribution package" is clearly outdated, as the Yocto delivery mentionned in the exemple is Kirkstone (should be now Mickledore) and the step : 
Replace STM32MP_MX_BASE by STM32MP_MY_DEMO_BASE
Is impossible to do, as the variable STM32MP_MX_BASE does not exist in latest machine configurations.
In the meanwhile, any ideas of how to implement this solution for latest? I'm currently using this solution "How to create your own machine" in the wiki, but that is not the way I would like to work in the long term.
