Subject: [PATCH 2/7] arm64: dts: ti: k3-j721e-common-proc-board: Add mailboxes to C66x DSPs
Date: Wed, 19 Aug 2020 20:03:26 -0500 [thread overview]
Message-ID: <20200820010331.2911-3-s-anna@ti.com> (raw)
In-Reply-To: <20200820010331.2911-1-s-anna@ti.com>
Add the required 'mboxes' property to both the C66x DSP processors on the
TI J721E common processor board. The mailboxes and some shared memory
are required for running the Remote Processor Messaging (RPMsg) stack
between the host processor and each of the R5Fs. The chosen sub-mailboxes
match the values used in the current firmware images. This can be changed,
if needed, as per the system integration needs after making appropriate
changes on the firmware side as well.
