ARM: dts: Add basic device tree support for omap2430 sdp

I doubt that there are many people using 2430 sdp, but as
that's been historically an important acid test platform
for omap2+ related changes, let's add minimal device
tree support for it.

If anybody is using it beyond minimal boot testing, patches
for more complete device tree support are welcome.

ARM: dts: Add basic Nokia N8X0 support

Add minimal device tree support for n8x0 boards so we
can make omap2 device tree only. Note that we still need
to initialize various platform data quirks to keep
things working until n8x0 drivers support device tree.

Here's a rough todo list for the people using n8x0:

1. Update menelaus for device tree and set up
   regulators at least for the MMC driver

2. Remove the MMC regulator platform data callback
   by using the Menlaus regulators directly in the
   driver passed from the .dts file

3. Update GPMC connected devices for onenand and
   tusb6010 for device tree

We're planning to remove all legacy platform data
for mach-omap2 over next few merge cycles, so if
people are still using n8x0, please fix the issues
above.

ARM: dts: Add basic support for omap3 LDP zoom1 labrador

Basic things like serial, Ethernet, MMC, NAND, DSS, touchscreen
and GPIO keys work.

For twl4030-keypad we're still missing the binding, but
support for that should be trivial to add once the driver
has been updated.

MUSB I'm pretty sure I got got to enumerate once, but I
suspect the battery charging somehow disrupts it and it's
not enumerating in general for some reason.

Patches are welcome to improve things if people are
still using this board.

For reference, here's some more info on this old board:

ARM: OMAP2+: Add support for board specific auxdata quirks

Looks like some boards need to fill in the auxdata before
we call of_platform_populate(). Let's add support for
auxdata quirks like we already have for pdata quirks for
legacy drivers.

ARM: OMAP2+: Make n8x0 behave better with device tree based booting

Initialize some devices using a late_initcall and test for

This way we can keep things working for legacy platform

ARM: OMAP2+: Remove legacy booting support for n8x0

Now we can boot n8x with the appended device tree with:

$ ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- make omap2420-n800.dtb
$ cat arch/arm/boot/zImage arch/arm/boot/dts/omap2420-n800.dtb > /tmp/zImage

Note that you need at least the following enabled:

CONFIG_ARM_APPENDED_DTB=y
CONFIG_ARM_ATAG_DTB_COMPAT=y
CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER=y
CONFIG_PINCTRL=y

ARM: OMAP2+: Remove board file for H4

The old 2420 based H4 is probably not used at all as 2420
was Nokia specific SoC. I have one, but I'm not using it because
of it's large size, and I doubt anybody else is using it either.

We do have minimal omap2420-h4.dts in place, so if anybody wants
more support on H4, patches are welcome.

So let's just remove it as that helps us making mach-omap2 to
be device tree only.

PCI: mvebu: Drop writes to bridge Secondary Status register

There are no writable bits in the secondary status register, only RO and
RW1C (write-1-to-clear) bits.  The driver never sets any of the RW1C bits,
so the status register should always be 0, just remove the set from the
write path.

Someday the RW1C bits should be copied/cleared directly from registers in
the HW.

PCI: mvebu: Obey bridge PCI_COMMAND_MEM and PCI_COMMAND_IO bits

When PCI_COMMAND_MEMORY/PCI_COMMAND_IO are cleared, the bridge should not
allocate windows or even look at the window limit/base registers.

Otherwise we may set up bogus windows while the PCI core code performs
discovery.  The core will leave PCI_COMMAND_IO cleared if it doesn't need
an IO window.

Have mvebu_pcie_handle_*_change respect the bits, and call the change
function whenever the bits changes.

PCI: mvebu: Support a bridge with no IO port window

Make pcie-io-aperture and the IO port MBUS ID in ranges optional.  If not
provided the bridge reports to Linux that IO space mapping is not supported
and refuses to configure an IO MBUS window.

This allows both complete disable (do not specify pcie-io-aperture) and
per-port disable (do not specify a IO target ranges entry for the port).

Most PCIe devices these days do not require IO support to function, so
having an option to disable it in the driver is useful.
