-From 08127ed36bad367903591bbf0f244179683ccb28 Mon Sep 17 00:00:00 2001
-From: John Crispin <blogic@openwrt.org>
-Date: Wed, 30 Mar 2011 09:27:49 +0200
-Subject: [PATCH 03/13] MIPS: Lantiq: Add PCI controller support.
-
-The Lantiq family of SoCs have a EBU (External Bus Unit). This patch adds
-the driver that allows us to use the EBU as a PCI controller. In order for
-PCI to work the EBU is set to endianess swap all the data. In addition we
-need to make use of SWAP_IO_SPACE for device->host DMA to work.
-
-The clock of the PCI works in several modes (internal/external). If this
-is not configured correctly the SoC will hang.
