> From: Igor Opaniuk <[email protected]> > i.MX 7's Cortex-M4 core can run from DDR and uses DDR memory for > the rpmsg communication. Both use cases need a fixed location of > memory reserved. For the rpmsg use case the reserved area needs > to be in sync with the kernel's hardcoded vring descriptor location. > Use the linux,usable-memory property to carve out 1MB of memory > in case the M4 core is running. Also make sure that the i.MX 7 > specific rpmsg driver does not get loaded in case we do not carve > out memory. > Signed-off-by: Stefan Agner <[email protected]> > Signed-off-by: Igor Opaniuk <[email protected]> > Signed-off-by: Igor Opaniuk <[email protected]> > Reviewed-by: Oleksandr Suvorov <[email protected]>
