From 9e0235e97ea2617beaacaa16ab5f0b9e75f4680e Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Wed, 30 Mar 2011 09:27:47 +0200
Subject: [PATCH 01/13] MIPS: Lantiq: Add initial support for Lantiq SoCs
Add initial support for Mips based SoCs made by Lantiq. This series will add
support for the XWAY family.
The series allows booting a minimal system using a initramfs or NOR. Missing
drivers and support for Amazon and GPON family will be provided in a later
series.
[Ralf: Remove some cargo cult programming and fixed formatting.]

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.

From f9391211e47cdcc31f341d710efef4b3b46c333d Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Wed, 30 Mar 2011 09:27:56 +0200
Subject: [PATCH 08/13] MIPS: Lantiq: Add more gpio drivers
The XWAY family allows to extend the number of gpios by using shift registers or latches. This patch adds the 2 drivers needed for this. The extended gpios are output only.
[ralf@linux-mips.org: Fixed ltq_stp_probe section() attributes.]

Subject: [PATCH 11/13] MIPS: Lantiq: Add ethernet driver
This patch adds the driver for the ETOP Packet Processing Engine (PPE32)
found inside the XWAY family of Lantiq MIPS SoCs. This driver makes 100MBit
ethernet work. Support for all 8 dma channels, gbit and the embedded switch
found on the ar9/vr9 still needs to be implemented.
