Subject: [PATCH 2/4] arm64: dts: ti: k3-am62a-mcu: Add R5F remote proc node
Date: Mon, 27 Jan 2025 16:16:29 -0600 [thread overview]
Message-ID: <20250127221631.3974583-3-jm@ti.com> (raw)
In-Reply-To: <20250127221631.3974583-1-jm@ti.com>
From: Hari Nagalla <hnagalla@ti.com>
AM62A SoCs have a single R5F core in the MCU voltage domain. The MCU
domain also has a 512KB sram memory, the R5F core can use for
applications needing fast memory access.
