[PATCH v2 1/6] ARM: dts: stm32: Add boot phase tags for STMicroelectronics f4 boards
Patrice Chotard

Fri Nov 14 09:26:01 PST 2025
The bootph-all flag was introduced in dt-schema
(dtschema/schemas/bootph.yaml) to define node usage across
different boot phases.
To ensure SD boot, timer, gpio, syscfg, clock and uart nodes need to be
present in all boot stages, so add missing bootph-all phase flag
to these nodes to support SD boot.
