Thomas Petazzoni d7d5a43c0d ARM: mvebu: fix overlap of Crypto SRAM with PCIe memory window
When the Crypto SRAM mappings were added to the Device Tree files
describing the Armada XP boards in commit c466d997bb ("ARM: mvebu:
define crypto SRAM ranges for all armada-xp boards"), the fact that
those mappings were overlaping with the PCIe memory aperture was
overlooked. Due to this, we currently have for all Armada XP platforms
a situation that looks like this:

Memory mapping on Armada XP boards with internal registers at
0xf1000000:

 - 0x00000000 -> 0xf0000000	3.75G 	RAM
 - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
 - 0xf1000000 -> 0xf1100000	1M	internal registers
 - 0xf8000000 -> 0xffe0000	126M	PCIe memory aperture
 - 0xf8100000 -> 0xf8110000	64KB	Crypto SRAM #0	=> OVERLAPS WITH PCIE !
 - 0xf8110000 -> 0xf8120000	64KB	Crypto SRAM #1	=> OVERLAPS WITH PCIE !
 - 0xffe00000 -> 0xfff00000	1M	PCIe I/O aperture
 - 0xfff0000  -> 0xffffffff	1M	BootROM

The overlap means that when PCIe devices are added, depending on their
memory window needs, they might or might not be mapped into the
physical address space. Indeed, they will not be mapped if the area
allocated in the PCIe memory aperture by the PCI core overlaps with
one of the Crypto SRAM. Typically, a Intel IGB PCIe NIC that needs 8MB
of PCIe memory will see its PCIe memory window allocated from
0xf80000000 for 8MB, which overlaps with the Crypto SRAM windows. Due
to this, the PCIe window is not created, and any attempt to access the
PCIe window makes the kernel explode:

[    3.302213] igb: Copyright (c) 2007-2014 Intel Corporation.
[    3.307841] pci 0000:00:09.0: enabling device (0140 -> 0143)
[    3.313539] mvebu_mbus: cannot add window '4:f8', conflicts with another window
[    3.320870] mvebu-pcie soc:pcie-controller: Could not create MBus window at [mem 0xf8000000-0xf87fffff]: -22
[    3.330811] Unhandled fault: external abort on non-linefetch (0x1008) at 0xf08c0018

This problem does not occur on Armada 370 boards, because we use the
following memory mapping (for boards that have internal registers at
0xf1000000):

 - 0x00000000 -> 0xf0000000	3.75G 	RAM
 - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
 - 0xf1000000 -> 0xf1100000	1M	internal registers
 - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0 => OK !
 - 0xf8000000 -> 0xffe0000	126M	PCIe memory
 - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
 - 0xfff0000  -> 0xffffffff	1M	BootROM

Obviously, the solution is to align the location of the Crypto SRAM
mappings of Armada XP to be similar with the ones on Armada 370, i.e
have them between the "internal registers" area and the beginning of
the PCIe aperture.

However, we have a special case with the OpenBlocks AX3-4 platform,
which has a 128 MB NOR flash. Currently, this NOR flash is mapped from
0xf0000000 to 0xf8000000. This is possible because on OpenBlocks
AX3-4, the internal registers are not at 0xf1000000. And this explains
why the Crypto SRAM mappings were not configured at the same place on
Armada XP.

Hence, the solution is two-fold:

 (1) Move the NOR flash mapping on Armada XP OpenBlocks AX3-4 from
     0xe8000000 to 0xf0000000. This frees the 0xf0000000 ->
     0xf80000000 space.

 (2) Move the Crypto SRAM mappings on Armada XP to be similar to
     Armada 370 (except of course that Armada XP has two Crypto SRAM
     and not one).

After this patch, the memory mapping on Armada XP boards with
registers at 0xf1 is:

 - 0x00000000 -> 0xf0000000	3.75G 	RAM
 - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
 - 0xf1000000 -> 0xf1100000	1M	internal registers
 - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0
 - 0xf1110000 -> 0xf1120000	64KB	Crypto SRAM #1
 - 0xf8000000 -> 0xffe0000	126M	PCIe memory
 - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
 - 0xfff0000  -> 0xffffffff	1M	BootROM

And the memory mapping for the special case of the OpenBlocks AX3-4
(internal registers at 0xd0000000, NOR of 128 MB):

 - 0x00000000 -> 0xc0000000	3G 	RAM
 - 0xd0000000 -> 0xd1000000	1M	internal registers
 - 0xe800000  -> 0xf0000000	128M	NOR flash
 - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0
 - 0xf1110000 -> 0xf1120000	64KB	Crypto SRAM #1
 - 0xf8000000 -> 0xffe0000	126M	PCIe memory
 - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
 - 0xfff0000  -> 0xffffffff	1M	BootROM

Sudeep Holla 8b44f5be20 ARM: dts: armada: replace isil, irq2-can-wakeup-machine with wakeup-source property
Though the driver will continue to check for and support the legacy
"isil,irq2-can-wakeup-machine" boolean property to wakeup source,
"wakeup-source" is the new standard binding.

This patch replaces the legacy "isil,irq2-can-wakeup-machine" with the
unified "wakeup-source" property in order to avoid any futher copy-paste
duplication.

Arnaud Ebalard 784693def2 arm: mvebu: disable unused Armada RTC on ReadyNAS 102, 104 and 2120
By default, armada-370-xp.dtsi file has internal RTC enabled.
NETGEAR ReadyNAS 102, 104 and 2120 all use an Intersil ISL12057
I2C RTC chip. The internal RTC not being disabled in the .dts
files of those devices result in the following useless first
line during boot:

This patch marks Armada internal RTC as disabled in individual .dts

Linus Torvalds a233bb742a ARM: SoC DT updates
DT changes continue to be the bulk of our merge window contents.
 
 We continue to have a large set of changes across the board as new platforms
 and drivers are added.
 
 Some of the new platforms are:
 - Alphascale ASM9260
 - Marvell Armada 388
 - CSR Atlas7
 - TI Davinci DM816x
 - Hisilicon HiP01
 - ST STiH418
 
 There have also been some sweeping changes, including relicensing of DTS
 contents from GPL to GPLv2+/X11 so that the same files can be reused in
 other non-GPL projects more easily. There's also been changes to the
 DT Makefile to make it a little less conflict-ridden and churny down
 the road.

Arnaud Ebalard 1a67e256db ARM: mvebu: ISL12057 rtc chip can now wake up RN102, RN102 and RN2120
Now that alarm support for ISL12057 chip is available w/ the specific
"isil,irq2-can-wakeup-machine" property, let's use that feature of the
driver dedicated to NETGEAR ReadyNAS 102, 104 and 2120 specific routing of
RTC Alarm IRQ#2 pin; on those devices, this pin is not connected to the
SoC but to a PMIC, which allows the device to be powered up when RTC alarm
rings.

For that to work, the chip needs to be explicitly marked as a device
wakeup source using this "isil,irq2-can-wakeup-machine" boolean property.
This makes 'wakealarm' sysfs entry available to configure the alarm.

NASDAQ symbol, isil, should not hurt.

Arnaud Ebalard 500abb6ccb ARM: mvebu: Netgear RN2120: Use Hardware BCH ECC
The bootloader on the Netgear ReadyNAS RN2120 uses Hardware BCH
ECC (strength = 4), while the pxa3xx NAND driver by default uses
Hamming ECC (strength = 1).

This patch changes the ECC mode on these machines to match that
of the bootloader and of the stock firmware. That way, it is
now possible to update the kernel from userland (e.g. using
standard tools from mtd-utils package); u-boot will happily
load and boot it.

The issue was initially reported and fixed by Ben Pedell for
RN102. The RN2120 shares the same Hynix H27U1G8F2BTR NAND
flash and setup. This patch is based on Ben's fix for RN102.

Thomas Petazzoni 953f9c5d7c ARM: mvebu: don't use clocks property in UART node for Netgear RN2120
The Netgear RN2120 was not using the same strategy as the other Armada
370/375/38x/XP boards: it was using a 'clocks' property and not the
'clock-frequency' property in its UART controller Device Tree node.

However, now that this clock reference is present at the SoC-level,
there is no point in duplicating it at the board-level.

Now that support for Intersil ISL12057 RTC chip is available
upstream, let's enable it in NETGEAR ReadyNAS 2120 .dts file
so that the device stop believing it's the 70's.

Arnaud Ebalard ad51eddd95 ARM: mvebu: Enable NAND controller in ReadyNAS 2120 .dts file
Now that NAND controller support is available for Armada XP
(cb28e2537a6f: ARM: mvebu: Add support for NAND controller in
Armada 370/XP), this patch enables support for ReadyNAS 2120
and defines default partition layout as delivered by NETGEAR.

As described in similar commits 2be2bc39c6 (ARM: mvebu: Enable
NAND controller in Armada XP GP board) and d8c552dddf (ARM:
mvebu: Enable NAND controller in Armada 370 Mirabox),
"marvell,keep-config" parameter is used as current support does
not allow for setting of timing parameters yet.

Arnaud Ebalard 8aa0b019fe ARM: mvebu: Add Netgear ReadyNAS 2120 board
All hardware parts of the (mv78230 Armada XP based) NETGEAR ReadyNAS
2120 are supported by mainline kernel (USB 3.0 and eSATA rear ports,
USB 2.0 front port, Gigabit controller and PHYs for the two rear ports,
serial port, LEDs, Buttons, 88SE9170 SATA controllers, three G762 fan
controllers, G751 temperature sensor) except for:

 - the Intersil ISL12057 I2C RTC Chip,
 - the Armada NAND controller.

Support for both of those is currently work in progress and does not
prevent boot.
