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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
