This is a bug in drivers/remoteproc/rcar_rproc.c: struct rproc_mem_entry { void *va; static int rcar_rproc_mem_alloc(struct rproc *rproc, struct rproc_mem_entry *mem) { void *va; va = ioremap_wc(mem->dma, mem->len); This is a bug. static int rcar_rproc_mem_release(struct rproc *rproc, struct rproc_mem_entry *mem) { iounmap(mem->va); This is also a bug. drivers/remoteproc/rcar_rproc.c needs fixing not to ignore the __iomem annotation when dealing with iomem. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
