From ef1876ff76096b3cad6fdb8b797226e4914f5726 Mon Sep 17 00:00:00 2001 From: Hari Nagalla Date: Thu, 3 Oct 2024 12:01:16 -0500 Subject: [PATCH] arm64: dts: ti: k3-am64: Add M4F remoteproc node 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.
