Subject: [PATCH v2 3/3] riscv: dts: starfive: jh7110: bootph-pre-ram hinting needed by boot loader
Date: Fri, 15 Aug 2025 00:37:23 -0700 [thread overview]
Message-ID: <20250815073739.79241-4-e@freeshell.de> (raw)
In-Reply-To: <20250815073739.79241-1-e@freeshell.de>
Add bootph-pre-ram hinting to jh7110.dtsi:
- CPU interrupt controller(s)
- core local interrupt timer
- DDR memory controller
- oscillator
- syscrg clock-controller
