From 5411ad27dba1e59923f3865f90ab756fd6b9ab3c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 19 Jul 2018 05:54:39 -0700 Subject: microblaze: use generic dma_noncoherent_ops Switch to the generic noncoherent direct mapping implementation. This removes the direction-based optimizations in sync_{single,sg}_for_{cpu,device} which were marked untestested and do not match the usually very well tested {un,}map_{single,sg} implementations.
