Could you check once , if this is duplicated

commit fbdb8aa4eab84 "arm64: dts: ti: k3-j721e-evm*: Add bootph-* 
properties"

adds bootph-all in arch/arm64/boot/dts/ti/k3-j721e-som-p0.dtsi file for 
flash.

AFAIK, parent node should inherit property of child for bootph.

In case you are not getting in u-boot then u-boot shall fix this[0]
