Subject: [PATCH v11 6/9] arm64: dts: ti: k3-am64: Add M4F remoteproc node
Date: Fri, 2 Aug 2024 10:21:06 -0500 [thread overview]
Message-ID: <20240802152109.137243-7-afd@ti.com> (raw)
In-Reply-To: <20240802152109.137243-1-afd@ti.com>
From: Hari Nagalla <hnagalla@ti.com>
The AM64x SoCs of the TI K3 family have a Cortex M4F core in the MCU
domain. This core can be used by non safety applications as a remote
processor. When used as a remote processor with virtio/rpmessage IPC,
two carveout reserved memory nodes are needed.
Disable by default as this node is not complete until mailbox data
is provided in the board level DT.
