[ARM] 4090/2: avoid clash between PXA and SA1111 defines

The Lubbock platform uses both a PXA25x and a SA1111 at the same time.
Both chips have the same "Serial Audio Controller" registers although
the SA1111 one is never expected to be used in preference to the PXA25x
one. So let's disable the SA1111 defines whenever compilation is for a
PXA architecture and make the PXA defines always defined.

This removes a bunch of "already defined" warnings as well since the
current hack to prevent them depended on include ordering which wasn't
always right.

While at it, clean up the SA1111 defines allowing to get rid of the
__CCREG() macro.

The current implementation only assumes one GIC to be present in the
system. However, there are platforms with more than one cascaded interrupt
controllers (RealView/EB MPCore for example).

If RTS interrupt is caused by RTS senzing logic inside i.MX UART module the

It applies only for interrupts going through GPIO layer.  The problem has

  No IRQF_TRIGGER set_type function for IRQ 26 (MPU)

I would not change type to fixed 0, because it could be possible to use
different GPIO MX1 pin for RTS in the theory.  On the other hand it is only

[ARM] 4154/1: AT91: Clock update

Unconditionally disabling the PCKs (Programmable Clocks) is not a good
idea as it breaks boards that depend on those clocks being enabled by
bootloaders.
Therefore only disable unused clocks late in the init process, giving
the board init code the chance to claim the clock.

Patch from Steven Scholz.

Since the HCK clocks on SAM9261 are already being registered as a
independent clocks, we don't need the special case for HCK0 on the
SAM9261.  Platform-init code and drivers should use the clock API to
enable/disable the clock.

The Atmel AT91 and AVR32 processor architectures share many of the same
peripherals.  The PDC (Peripheral Data Controller) registers are also
implemented within in a number of the on-chip peripherals (eg, USART,
MMC, SPI, SSC, etc).

In a attempt not to duplicate the register definitions in each
peripheral, or in each architecture, the at91_pdc.h header in
asm-arm/arch-at91 and asm-avr32/arch-at32ap has been replaced with
linux/atmel_pdc.h.

The definitions have also been renamed from AT91_PDC_* to ATMEL_PDC_*,
and the drivers updated accordingly.

[ARM] 4141/1: consolidate functions that handles gpio in pxa2xx_udc

This patch renames pxa_gpio_set/get functions defined in drivers/usb/gadget/pxa2xx_udc.h to udc_gpio_set/get.

These functions are moved from drivers/usb/gadget/pxa2xx_udc.h to include/asm-arm/arch-pxa2xx/udc.h

Creates new functions: udc_gpio_to_irq, udc_gpio_init_vbus, udc_gpio_init_pullup in include/asm-arm/arch-pxa2xx/udc.h. These functions are used in drivers/usb/gadget/pxa2xx_udc.c instead of direct low-level (pxa2xx only) functions.

Creates all these udc_gpio_* functions in include/asm-arm/arch-ixp4xx/udc.h. This implementation has no real code because ixp4xx doesn't use vbus - only vbus uses all these gpio functions (and because ixp4xx misses any function which converts number of gpio pin into it's irq).

This is next step to make pxa2xx_udc fully work on ixp4xx platform.

[ARM] 4143/1: AT91: Prepare for AT91SAM9263 support

The Atmel AT91SAM9263 processor includes many more integrated
peripherals than Atmel's previous ARM9-based AT91 processors, so this
has necessitated a few changes to the core AT91 support.

These changes are:
      * The system peripheral I/O region we remap has increased from
        0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF.
      * The increased I/O region forces changes to entry-macro.S and
        debug-macro.S due to ARM's limited immediate offset addressing
        modes.
      * Maximum number of GPIO banks increases to 5.
      * 2 MMC controllers so the board-setup code needs to specify which
        controller it wishes to use when calling at91_add_device_mmc().

Fix build failure of AT91SAM9260.

The AT91RM9200 ethernet driver (at91_ether.c) stores platform data in a
"struct at91_eth_data" structure, but the AT91SAM9260 (and AT91SAM9263)
ethernet driver (macb.c) [developed on the AVR32 architecture] expects a
"struct eth_platform_data".

Since the platform data of the two drivers is very similar, we continue
to use the "struct at91_eth_data" for all AT91 processors but add a
    #define eth_platform_data      at91_eth_data
in board.h to keep the MACB driver happy.
