[PATCH 1/4] arm: dts: Refactor common dtsi file for R5 and A53 SPL

Nitin Yadav n-yadav at ti.com
Wed Sep 27 10:21:02 CEST 2023


Add k3-am62x-r5-sk-common to include nodes common for R5
SPL from k3-am625-r5-sk for AM62x SoC based boards. Add
k3-am62x-sk-common-u-boot to move common nodes of A53 SPL
stage from k3-am625-sk-u-boot.
