The K3 J722S-EVM platform is based on the J722S SoC which has one
single-core Arm Cortex-R5F processor in each of the WAKEUP, MCU and MAIN
voltage domain, and two C71x DSP subsystems in MAIN voltage domain.
The Inter-Processor communication between the A72 cores and these R5F
Should be A53 core not A72
and DSP remote cores is achieved through shared memory and Mailboxes.
Thus, add the memory carveouts and enable the mailbox clusters required
for communication.
Also, The remoteproc firmware like of R5F and DSPs in the MAIN voltage
domain use timers. Therefore, change the status of the timer nodes to
"reserved" to avoid any clash during booting of remotecores. Usage is
described as below:
+===================+=============+
| Remoteproc Node | Timer Node |
+===================+=============+
| main_r5fss0_core0 | main_timer0 |
+-------------------+-------------+
| c7x_0 | main_timer1 |
+-------------------+-------------+
| c7x_1 | main_timer2 |
+-------------------+-------------+
