[PATCH V4] remoteproc: imx_rproc: Ignore create mem entry for resource table

From: Peng Fan (OSS)
Date: Thu Apr 14 2022 - 22:56:04 EST


From: Peng Fan <peng.fan@xxxxxxx>

Resource table is used by Linux to get information published by
remote processor. It should be not be used for memory allocation, so
not create rproc mem entry.
