Add GPIO led support: J2 to either block of LEDs on the STK1000.

This uses the new LEDS_GPIO driver, and sets up a heartbeat trigger by
default ... either bright (!!) amber, or a more interesting purple.

The STK1000 uses pullups on the MDIO lines to the PHY, but they are
too weak. This causes the PHY layer to detect PHYs on all possible MII
addresses. Mask out all but the correct address to prevent this from
happening.

This adds some STK1002-specific config options covering the jumper settings,
so the kernel can automatically be configured to include the relevant devices.

One of them replaces the previous internal SW2_DEFAULT setting; SPI config
is affected by two of the jumpers; and a fourth one switches between LCD and
the second Ethernet connector.  (There's more that to be done.)

In the latest incarnation of the ltv350qv driver the call to
spi_setup() has been removed. So we need to initialize things more
carefully in the board info struct.

This modifies and extends the existing lcdc platform code to support
the new atmel_lcdfb driver. The ATSTK1000 board code is set up to use
the on-board Samsung LTV350QV LCD panel.

Since the core setup code takes care of both allocation and
reservation of framebuffer memory, there's no need for this board-
specific hook anymore. Replace it with two global variables,
fbmem_start and fbmem_size, which can be used directly.

Set up one spi_board_info array per controller and pass this to
at32_add_device_spi so that it can set up any GPIO pins for chip
selects based on this information.

The PIOE device was left out before because it muxes SDRAM pins (and
is therefore a bit dangerous to mess with) and because no existing
drivers had any use for it.

It is needed for CompactFlash, however, and now that we have a way
to protect the SDRAM pins, it can be safely added.

Fixes to USART setup on the stk-1000 ... don't configure USART 2, since
its TXD/RXD are used for INT-A and INT-B buttons; and configure USART 0
(for IRDA, and with corrected IRQ) iff SW2 has a non-default setting.

The macb driver will probe for the PHY chip and read the mac address
from the MACB registers, so we don't need them in eth_platform_data
anymore.

Since u-boot doesn't currently initialize the MACB registers with the
mac addresses, the tag parsing code is kept but instead of sticking
the information into eth_platform_data, it uses it to initialize
the MACB registers (in case the boot loader didn't do it.) This code
should be unnecessary at some point in the future.

By moving the ethernet tag parsing to the board-specific code we avoid
the issue of figuring out which device we're supposed to attach the
information to.  The board specific code knows this because it's
where the actual devices are instantiated.

Allow the board to remap actual USART peripheral devices to serial
devices by calling at32_map_usart(hw_id, serial_line). This ensures
that even though ATSTK1002 uses USART1 as the first serial port, it
will still have a ttyS0 device.

This also adds a board-specific early setup hook and moves the
at32_setup_serial_console() call there from the platform code.

This adds support for the Atmel AVR32 architecture as well as the AT32AP7000
CPU and the AT32STK1000 development board.

AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for
cost-sensitive embedded applications, with particular emphasis on low power
consumption and high code density.  The AVR32 architecture is not binary
compatible with earlier 8-bit AVR architectures.

The AVR32 architecture, including the instruction set, is described by the
AVR32 Architecture Manual, available from

http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf

The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture.  It
features a 7-stage pipeline, 16KB instruction and data caches and a full
Memory Management Unit.  It also comes with a large set of integrated
peripherals, many of which are shared with the AT91 ARM-based controllers from
Atmel.

Full data sheet is available from

http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf

while the CPU core implementation including caches and MMU is documented by
the AVR32 AP Technical Reference, available from

http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf

Information about the AT32STK1000 development board can be found at

http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918

including a BSP CD image with an earlier version of this patch, development
tools (binaries and source/patches) and a root filesystem image suitable for
booting from SD card.

Alternatively, there's a preliminary "getting started" guide available at
http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links
to the sources and patches you will need in order to set up a cross-compiling
environment for avr32-linux.

This patch, as well as the other patches included with the BSP and the
toolchain patches, is actively supported by Atmel Corporation.
