Subject: [PATCH v5 1/3] arm64: dts: ti: k3-j784s4: Add phase tags marking
Date:   Sat, 12 Aug 2023 00:50:28 +0530

bootph-all as phase tag was added to dt-schema
(dtschema/schemas/bootph.yaml) to cover U-Boot challenges with DT.
That's why add it also to Linux to be aligned with bootloader requirement.

On TI K3 J784S4 SoC, only secure_proxy_mcu and secure_proxy_sa3 nodes are
exclusively used by R5 bootloader, rest of the dts nodes with bootph-* are
used by later boot stages also.

And secure_proxy_mcu and secure_proxy_sa3 are disabled in kernel device
tree, and will be only enabled in R5 bootloader device tree.
So, bootph-pre-ram for secure_proxy_mcu and secure_proxy_sa3 will be
added in R5 bootloader device tree only.

Add bootph-all for all other nodes that are used in the bootloader on
K3 J784S4 SoC, and bootph-pre-ram is not needed specifically for any node
in kernel dts.
