[PATCH 1/3] arm64: dts: ti: k3-am64: Add phase tags marking
From: Nishanth Menon
Date: Mon Sep 11 2023 - 18:24:27 EST
bootph-all as phase tag was added to dt-schema
(dtschema/schemas/bootph.yaml) to describe various node usage during
boot phases with DT.
On TI K3 AM642 SoC, only esm nodes are exclusively used by R5
bootloader, rest of the dts nodes with bootph-* are used by later boot
stages also.
Add bootph-all for all other nodes that are used in the bootloader on
K3 AM642 SoC, and bootph-pre-ram is not needed specifically for any
other node in kernel dts.
