The Marvell Orion is a family of ARM SoCs with a DDR/DDR2 memory
controller, 10/100/1000 ethernet MAC, and USB 2.0 interfaces,
and, depending on the specific model, PCI-E interface, PCI-X
interface, SATA controllers, crypto unit, SPI interface, SDIO
interface, device bus, NAND controller, DMA engine and/or XOR
engine.
This contains the basic structure and architecture register definitions.

The Feroceon is a family of independent ARMv5TE compliant CPU core
implementations, supporting a variable depth pipeline and out-of-order
execution. The Feroceon is configurable with VFP support, and the
later models in the series are superscalar with up to two instructions
per clock cycle.
This patch adds the initial low-level cache/TLB handling for this core.

'select' used by config symbol 'INTEL_IOATDMA' refers to undefined symbol 'DCA'
Although drivers/dma is currently the only user future drivers outside of
drivers/dma may select this option so it is better to add this to
arch/arm/Kconfig than move DCA to drivers/dma/Kconfig.

Commit 09cadedbdc ("Combine
instrumentation menus in kernel/Kconfig.instrumentation") broke ARM
profiling support, since ARM has some extra Kconfig options and doesn't
just use the common OPROFILE/KPROBES config options.
Rather than just revert the thing outright, or add ARM-specific
knowledge to the generic Kconfig.instrumentation file (where the only
and whole point was to be generic, not too architecture-specific), this
just makes ARM not use the generic version, since it doesn't suit it.
So create an arm-specific version of Kconfig.instrumentation instead,
and use that.

Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.
Because this is a consolidation of a couple old missed patches, it touches both

Quoting Randy:
"It seems sad that this patch sources Kconfig.marker, a 7-line file,
20-something times. Yes, you (we) don't want to put those 7 lines into
20-something different files, so sourcing is the right thing.
However, what you did for avr32 seems more on the right track to me: make
_one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES,
and MARKERS and then use (source) that in all of the arches."

Bugfixes for the OSK led support:
- Fix Kconfig merge glitches: Mistral handles idle and timer leds just fine
- Fix pm_suspend() runtime botch: can't sleep, so can't touch tps65010 leds
Improvements:
- Switch sense of Mistral idle led, so idle == off
Probably the TPS65010 leds should be handled only by the "new led" API.

Support for generic input output for MX1 family.
The implementation prevents allocation of one pin
by two users, but does not store pointer to the user
description permanently, because this solution
would have bigger memory overhead.
The simple way to integrate code with per BSP
pins setup and allocation is required else all GPIO
registration checking is useless. The function
imx_gpio_setup_multiple_pins() can be used for this
purpose in future.
