Subject: [PATCH v3 3/3] arm64: dts: ti: k3-j784s4-evm: Reserve memory for remote proc IPC
Reserve memory for remote processors. Two memory regions are reserved
for each remote processor. The first 1Mb region is used for virtio
Vring buffers for IPC and the second region is used for holding
resource table, trace buffer and as external memory to the remote
processor. The mailboxes are also assigned for each remote processor.
