a38de083d2 AVR32: Move addrspace.h to arch-directory, and move some functions from io.h to addrspace.h
The AVR32A architecture (which AT32UC3A-series is based on) has a
different memory layout than the AVR32B-architecture. This patch moves
addrspace.h to an arch-dependent directory in preparation for
AT32UC3A-support. It also moves some address-space manipulation
functions from io.h to addrspace.h.

1de97f9856 Eliminated arch-specific mmc header requirement
The current MMC infrastructure relies on the existence of an
arch-specific header file.  This isn't necessary, and a couple
drivers were forced to implement dummy files to meet this requirement.
Instead, we move the stuff in those header files into a more appropriate
place, and eliminate the stubs and the #include of asm/arch/mmc.h

65e43a1063 Introduce virt_to_phys()
virt_to_phys() returns the physical address given a virtual. In most
cases this will be just the input value as the vast majority of
systems run in a 1:1 mode.

However in systems that are not running this way it should report the
physical address or ~0 if no mapping exists for the given virtual

36d375faf5 avr32: Use board_postclk_init instead of gclk_init
Replace the avr32-specific gclk_init() board hook with the standard
board_postclk_init() hook which is supposed to run at the same point
during initialization.

Provide a dummy weak alias for boards not implementing this hook. The
cost of this is:
  - 2 bytes for the dummy function (retal 0)
  - 2 bytes for each unnecessary function call (short rcall)

which is a pretty small price to pay for avoiding lots of #ifdef
clutter. In this particular case, all boards probably end up slightly
smaller because we avoid the conditional checking if the gclk_init
symbol is NULL.

ab0df36fc7 avr32: refactor the portmux/gpio code
- Separate the portmux configuration functionality from the GPIO pin
    control API.
  - Separate the controller-specific code from the chip-specific code.
  - Allow "ganged" port configuration (multiple pins at once).
  - Add more flexibility to the "canned" peripheral select functions:
      - Allow using more than 23 address bits, more chip selects, as
	well as NAND- and CF-specific pins.
      - Make the MACB SPEED pin optional, and choose between MII/RMII
	using a parameter instead of an #ifdef.
      - Make it possible to use other MMC slots than slot 0, and support
	different MMC/SDCard data bus widths.
  - Use more reasonable pull-up defaults; floating pins may consume a
    lot of power.
  - Get rid of some custom portmux code from the mimc200 board code. The
    old gpio/portmux API couldn't really handle its requirements, but
    the new one can.
  - Add documentation.

The end result is slightly smaller code for all boards. Which isn't
really the point, but at least it isn't any larger.

This has been verified on ATSTK1002 and ATNGW100. I'd appreciate if
the board maintainers could help me test this on their boards. In
particular, the mimc200 port has lost a lot of code, so I'm hoping Mark
can help me out.

5c374c9ee1 Add support for the hammerhead (AVR32) board
The Hammerhead platform is built around a AVR32 32-bit microcontroller
from Atmel.  It offers versatile peripherals, such as ethernet, usb
device, usb host etc.

The board also incooperates a power supply and is a Power over Ethernet
(PoE) Powered Device (PD).

Additonally, a Cyclone III FPGA from Altera is integrated on the board.
The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two
DDR2 SDRAM interfaces, which will cover even the most exceptional need
of memory bandwidth. Together with the onboard video decoder the board
is ready for video processing.

Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on
32bit targets.

GCC can be made to warn about usage of long long types with ISO C90
(-ansi), but only with -pedantic.  You can write this in a way that even
then it doesn't cause warnings, namely by:

#ifdef __GNUC__
__extension__ typedef __signed__ long long __s64;
__extension__ typedef unsigned long long __u64;
#endif

The __extension__ keyword in front of this switches off any pedantic
warnings for this expression.

4d7d6936eb Introduce map_physmem() and unmap_physmem()
map_physmem() returns a virtual address which can be used to access a
given physical address without involving the cache. unmap_physmem()
should be called when the virtual address returned by map_physmem() is
no longer needed.

This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.
