From f2e74abfaad446765ce0350aed1d9c5eed5b1b36 Mon Sep 17 00:00:00 2001 From: Loic Pallardy Date: Fri, 27 Jul 2018 15:14:38 +0200 Subject: remoteproc: add release ops in rproc_mem_entry struct Memory entry could be allocated in different ways (ioremap, dma_alloc_coherent, internal RAM allocator...). This patch introduces a release ops in rproc_mem_entry structure to associate dedicated release mechanism to each memory entry descriptor in order to keep remoteproc core generic.
