Subject: [PATCH v3 4/4] riscv: dts: starfive: jh7110-common: bootph-pre-ram hinting needed by boot loader
Date: Fri, 2 May 2025 03:30:44 -0700 [thread overview]
Message-ID: <20250502103101.957016-5-e@freeshell.de> (raw)
In-Reply-To: <20250502103101.957016-1-e@freeshell.de>
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
- mmc0 for eMMC
- mmc1 for SD Card
- uart0 for serial console
With this the U-Boot SPL secondary program loader may drop such overrides.
