* Here we define the shared memory buffers for the RPMSG IPC back-end in simulation.
|
|
* In real HW, these are booked in RAM thru device tree configuration.
|
|
* In this simulated target, we just define them at build time to have the size defined
|
|
* in device tree.
|
|
*
|
|
* Note that this file is only compiled as part of the application core image, and therefore
|
|
* when the network core is built with the IPC service, we cannot produce an executable
|
|
* with the network core image alone, as we would lack this buffer during linking.
