Subject: [PATCH v2 2/3] arm64: dts: ti: k3-am642-evm/sk: Add mailboxes to R5Fs
Date: Tue, 15 Jun 2021 14:57:17 -0500	[thread overview]
Message-ID: <20210615195718.15898-3-s-anna@ti.com> (raw)
In-Reply-To: <20210615195718.15898-1-s-anna@ti.com>

Add the required 'mboxes' property to all the R5F processors for the
TI AM642 EVM and SK boards. 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.

Note that any R5F Core1 resources are needed and used only when that
R5F cluster is configured for Split-mode.
