[PATCH v2 5/5] riscv: dts: starfive: jh7110-common: bootph-pre-ram hinting needed by boot loader

From: E Shattow
Date: Sun Feb 02 2025 - 20:42:43 EST


Add bootph-pre-ram hinting to jh7110-common.dtsi:
- i2c5_pins and i2c-pins subnode for connection to eeprom
- eeprom node
- qspi flash configuration subnode
- memory node
- uart0 for serial console

With this the U-Boot SPL secondary program loader may drop such
overrides when using dt-rebasing with JH7110 OF_UPSTREAM board targets.
