Subject: [PATCH 0/2] arm64: dts: ti: k3-am65: add boot phases to critical
 nodes

Hello everyone!

To save precious on chip RAM space during bootup 'bootph-*' flags was 
added to the dt-schema to describe which nodes need to be present during 
each phase of the bootup process and which can be pruned to recover RAM 
space that would otherwise be wasted.

This small series adds the bootph-all flags to all the boot critical 
nodes for all boards that utilize the AM65x as well as to the AM65's 
reference board.

Happy Hacking
~Bryan
