From 0ea833c24999093be6369f9145333bd10acfad76 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Mon, 8 Jan 2018 18:16:34 +0000 Subject: sun4u: split IOMMU device out from apb.c to sun4u_iommu.c By separating the sun4u IOMMU device into new sun4u_iommu.c and sun4m_iommu.h files we noticeably simplify apb.c whilst bringing sun4u in line with all the other IOMMU-supporting architectures.
