60607c9de0 avr32: allow multi block mmc access for all boards
Commit 1db7377a70 fixes the gen_atmel_mci driver
to be able to use multi block access for avr32. Therefore remove the setting
which forces single block access.

This also adds a huge performace gain for mmc access:

72fa467988 ATMEL: use generic mmc framework
gen_atmel_mci works on AVR32 as well, so no need to use the legacy
mmc driver. This also has the nice side effect of being able to use
SDHC cards an those boards.

221786525f atstk100x: switch to common cfi driver
This patch removes the board implemenatation for flash driver which can now
safely switched to the common cfi driver.

Compile tested for all atstk100x boards, runtime tested on atstk1002.

1f36f73fe7 avr32: Add simple paging support
Use the MMU hardware to set up 1:1 mappings between physical and virtual
addresses. This allows us to bypass the cache when accessing the flash
without having to do any physical-to-virtual address mapping in the CFI
driver.

The virtual memory mappings are defined at compile time through a sorted
array of virtual memory range objects. When a TLB miss exception
happens, the exception handler does a binary search through the array
until it finds a matching entry and loads it into the TLB. The u-boot
image itself is covered by a fixed TLB entry which is never replaced.

This makes the 'saveenv' command work again on ATNGW100 and other boards
using the CFI driver, hopefully without breaking any rules.

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.

c37207d7f5 Fix printf() format problems with configurable prompts
U-Boot allows for configurable prompt strings using the
CONFIG_AUTOBOOT_PROMPT resp. CONFIG_MENUPROMPT definitions. So far,
the assumption was that any such user defined problts would contain
exactly one "%d" format specifier. But some boards did not.

To allow for flexible boot prompts without adding too complex code we
now allow to specify the whole list of printf() arguments in the user
definition. This is powerful, but requires a responsible user who
really understands what he is doing, as he needs to know for exanple
which variables are available in the respective context.

a23e277c4a avr32: Rework SDRAM initialization code
This cleans up the SDRAM initialization and related code a bit, and
allows faster booting.

  * Add definitions for EBI and internal SRAM to asm/arch/memory-map.h
  * Remove memory test from sdram_init() and make caller responsible
    for verifying the SDRAM and determining its size.
  * Remove base_address member from struct sdram_config (was sdram_info)
  * Add data_bits member to struct sdram_config and kill CFG_SDRAM_16BIT
  * Add support for a common STK1000 hack: 16MB SDRAM instead of 8.

55ac7a7490 avr32: stk1002 and ngw100 convergence
Make STK1002 and NGW100 boards act more alike:
  - STK boards can use as many arguments as NGW
  - STK boards don't need to manage FPGAs either
  - NGW commands should match STK ones

Also spell U-Boot right in prompts for STK1002 and NGW100.
