From 01be5d63fd4645eab1d05a7caa04462c11c8b7a1 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 27 Oct 2009 10:35:02 +0900 Subject: sh: Revamp PCI DMA coherence Kconfig bits. Leaving this configurable caused more trouble than it was ever worth, so just make it explicit. Boards that are verified one way or the other can fix up their selects accordingly. We presently default to non-coherent for most platforms.

Now that this contains a grand total of 1 Kconfig option, it's hardly worth keeping split out. Roll CONFIG_PCI back in to the top-level architecture Kconfig, along with the other bus types.
