From e8b5325ca3d01c512be6f04d587869a01e0ea59f Mon Sep 17 00:00:00 2001 From: Sergey Ryazanov Date: Sat, 30 Aug 2014 06:06:28 +0400 Subject: MIPS: make PCI_DMA_BUS_IS_PHYS=1 constant No one of supported MIPS machines has an IOMMU unit, so we can safely define PCI_DMA_BUS_IS_PHYS = 1. Also remove iommu flag from the pci controller structure, since it is useless.
