Subject: [PATCH v2 5/5] arm64: dts: ti: k3-am62a7-sk: Enable ipc with remote proc nodes
Date: Wed, 9 Aug 2023 19:58:50 -0500	[thread overview]
Message-ID: <20230810005850.21998-6-hnagalla@ti.com> (raw)
In-Reply-To: <20230810005850.21998-1-hnagalla@ti.com>

From: Devarsh Thakkar <devarsht@ti.com>

Reserve memory for remote rpoc IPC and bind the mailbox assignments
for each remote proc. Two memory regions are reserved for each
remote processor. The first region of 1Mb of memory is used for Vring
shared buffers and the second region is used as external memory to the
remote processor, resource table and as tracebuffer.
