Subject: [U-Boot] [PATCH v1 2/2] board: colibri_imx7: reserve DDR memory for Cortex-M4

> 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.
