I have added "bootph-all" property in the common file of J722S-EVM and 
AM62P5-SK since we are enabling Ethernet boot for both the boards. Are
you referring to move the nodes I have added in
"k3-am62p-j722s-common-main.dtsi" to respective board files,
"k3-am62p5-sk.dts" and "k3-j722s-evm.dts".

Regards,
Chintan.
