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.]

From 435de86088af82496bcba69165cd7422bb4622ec Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Fri, 6 May 2011 00:10:01 +0200
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.

+ help
+ IFX extension for reserving (splitting) cache ways among VPEs. You must
+ give kernel command line arguments vpe_icache_shared=0 or
+ vpe_dcache_shared=0 to enable splitting of icache or dcache
+ respectively. Then you can specify which cache ways should be
+ assigned to which VPE. There are total 8 cache ways, 4 each
+ for dcache and icache: dcache_way0, dcache_way1,dcache_way2,
+ dcache_way3 and icache_way0,icache_way1, icache_way2,icache_way3.
+
+ For example, if you specify vpe_icache_shared=0 and icache_way2=1,
+ then the 3rd icache way will be assigned to VPE0 and denied in VPE1.
+
+ For icache, software is required to make at least one cache way available
+ for a VPE at all times i.e., one can't assign all the icache ways to one
+ VPE.
+
+ By default, vpe_dcache_shared and vpe_icache_shared are set to 1
+ (i.e., both icache and dcache are shared among VPEs)

From 14ea48a5f5702ddc97425cbe520600e187e14e4a Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Thu, 11 Aug 2011 13:58:39 +0200
Subject: [PATCH 03/24] MIPS: lantiq: fix watchdogs timeout handling
The enable function was using the global timeout variable for local operations.
This resulted in the value of the global variable being corrupted, thus
breaking the code.

commit 1c388919d89ca35741e9c4d3255adf87f76f0c06
Author: Geert Uytterhoeven <geert@linux-m68k.org>
Date: Sat May 7 20:53:16 2011 +0200
resources: Add lookup_resource()
Add a function to find an existing resource by a resource start address.
This allows to implement simple allocators (with a malloc/free-alike API)
on top of the resource system.
