From 19ad53e498745416a77c0377cbb4ee771eedd35b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 22 May 2017 11:11:20 +0200 Subject: [PATCH] openrisc: remove arch-specific dma_supported implementation This implementation is simply bogus - openrisc only has a simple direct mapped DMA implementation and thus doesn't care about the address.
