bootph-all phase tag was added to dt-schema (dtschema/schemas/bootph.yaml)
to overcome u-boot dts challenges.
Add bootph-all property for all the nodes that are used in the SPL stage
along with later boot stages.
This series will be ported to the u-boot k3-j784s4 support patch series
for syncing, and was requested in its review process:
https://lore.kernel.org/u-boot/20230321155227.GV8135@bill-the-cat/
v3: Changelog:
1) Changed all the bootph-pre-ram to bootph-all, as only
secure_proxy_mcu and secure_proxy_sa3 are exclusively used by R5 SPL.
Rest of the nodes are also used by later boot stages.
2) Merged SoC dtsi changes in single patch.
3) Moved cbass_main and cbass_mcu_wkup bootph-all to k3-j784s4.dtsi
Link to v2:
https://lore.kernel.org/lkml/20230807185645.128751-1-a-nandan@ti.com/#t
v2 Changelog :
1) Added k3-am69-sk.dts bootph-pre-ram patch
2) Added bootph-pre-ram for wkup_pmx0 and ospi0
3) Added bootph-pre-ram for mcu_timer1
Link to v1:

Follow https://lore.kernel.org/all/48b554aef75d11e6ad2ef7d21f22accb35432112.1683034376.git.michal.simek@amd.com/
for example of proper commit message and subject line.
The patch content actually is easy to read since it is adding
bootph-all property - but we do have a few exceptions. Commit message
should explain the rational of the choices made. For example, you
probably need to use secure_proxy_sa3 to talk with tifs in-order to
boot and that is a pre-ram property and so on..
So, nice refresh in the right direction, but a bit more work to do.
Thanks for handling am69-sk :)..
