The AV96 is in fact an assembly of DH Electronics DHCOR SoM on top
of an AV96 reference board. Split the DTs to reflect that and make
sure to DHCOR SoM can be reused on other boards easily.

It is also highly recommended to configure the board for the DHCOM
make stm32mp15_dhcom_basic_defconfig
make DEVICE_TREE=stm32mp15xx-dhcor-avenger96
as that permits reusing the board code for the DH components, like
accessing and reading out the ethernet MAC from EEPROM.

Recommended or mandatory...

For my point of view

- board/st/stm32mp1 manage the ST board (STM32MP15x-DKX and STM32MP15x-EV1)
                                 Can be used as starting point for customer new board

- board/dhelectronics/dh_stm32mp1 manage the board based on DHCOR SoM or can be a starting point of SoM user
 
For AV96, the first upstream was directly based on ST board, but I agree : it is clearly not a perfect solution (MAC address issue for example)

=> support on this board should be in dh_stm32mp1 board or create a new board AV96 based on it.

And I need to continue to move in st/common the part common for all the STM32MP157 boards....

When this file will be removed ? why kept this file.....
I propose to completely remove this file (no device tree for same board)

Both work, the later provides more complete solution.

Backward compatibility, I'd keep it in for a release or two.
But if removing it is fine, then so be it.

That's actually included via the avenger96.dts, so should be OK.
Although I am not real happy with that.

See my first question about the defconfig.

Ok, today both work.

I use buildman to compile all the stm32mp15x target / defconfig, 
so for me it is not mandatory.

In his makefile, the 2 strategy exist 

	dtb-$(CONFIG_ARCH_....)

	dtb-$(CONFIG_TARGET_....)

I have no clear preference....

I just highlight that using TARGET avoid bad configuration
between defconfig and associated device tree.

Yes sorry.

Yes I prefer.
Except if maintainers of this file have a other opinion.

Ok, I miss that. 
I agree, it is unexpected.

It's a bit weird, I think this should be added to the list of things to
improve in the next cycle.
