This patch makes the various mach dirs that use the plat-orion time
code pass in timer and bridge addresses explicitly, instead of having
plat-orion get those values by including a mach dir include file --
the latter mechanism is problematic if you want to support multiple
ARM platforms in the same kernel image.

The security accelerator which can act as a puppet player for the crypto
engine requires its commands in the sram. This patch adds support for the
phys mapping and creates a platform device for the actual driver.

[ nico: renamed device name from "mv,orion5x-crypto" to "mv_crypto"
  so to match the module name and be more generic for Kirkwood use ]

This adds DSA switch instantiation hooks to the orion5x and the
kirkwood ARM SoC platform code, and instantiates the DSA switch
driver on the 88F5181L FXO RD, the 88F5181L GE RD, the 6183 AP GE
RD, the Linksys WRT350n v2, and the 88F6281 RD boards.

The Orion-1-90 (88F6183) is another member of the Orion SoC family,
which has a 16 bit DDR2 interface, one x1 PCIe port (configurable as
Root Complex or Endpoint), one 10/100/1000 ethernet interface, one
USB 2.0 port with PHY, one SPDIF/I2S interface, one SDIO interface,
one TWSI interface, two UARTs, one SPI interface, a NAND controller,
a crypto engine, and a 4-channel DMA engine.

Currently, orion5x uses a hardcoded timer tick rate of 166 MHz, but
the actual timer tick rate varies between different members of the SoC
family (and can vary based on strap pin settings).

This patch prepares for runtime determination of the timer tick rate.

The Kurobox Pro crashes when any of the PCI controller registers
are accessed.  This patch adds a function to the Orion PCI handling
code that board support code can call to disable enumerating the
PCI bus entirely, and makes the Kurobox Pro PCI-related init code
call this function.

The Cardbus connector does not have an IDSEL signal, and Cardbus
cards are always the intended target of configuration transactions
on their local PCI bus.  This means that if the Orion's PCI bus
signals are hooked up to a Cardbus slot, the same set of PCI
functions will will appear 31 times, for each of the PCI device
IDs 1-31 (ID 0 is the host bridge).

This patch adds a function to the Orion PCI handling code that board
support code can call to enable Cardbus mode.  When Cardbus mode is
enabled, configuration transactions on the PCI local bus are only
allowed to PCI IDs 0 (host bridge) and 1 (cardbus device).

Instead of having board code poke directly into the MPP configuration
registers, and separately calling orion5x_gpio_set_valid_pins() to
indicate which MPP pins can be used as GPIO pins, introduce a helper
function for configuring the roles of each of the MPP pins, and have
that helper function handle gpio validity internally.

This patch moves initialisation of EHCI/I2C/UART platform devices
from the common orion5x_init() into the board support code.

The rationale behind this is that only the board support code knows
whether certain peripherals have been brought out on the board, and
not initialising peripherals that haven't been brought out is
desirable for example:
- to reduce user confusion (e.g. seeing both 'eth0' and 'eth1'
  appear while there is only one ethernet port on the board); and
- to allow for future power savings (peripherals that have not
  been brought out can be clock gated off entirely).

The current orion5x board ->map_irq() routines check whether a
given bus number lives on the PCIe controller by comparing it with
the PCIe controller's primary bus number.  This doesn't work in
case there are multiple buses in the PCIe domain, i.e. if there
exists a PCIe bridge on the primary PCIe bus.

This patch adds a helper function (orion5x_pci_map_irq()) that
returns the IRQ number for the given PCI device if that device has
a hard-wired IRQ, or -1 otherwise, and makes each board's
->map_irq() function use this helper function.
