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.

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.

Many people run into problems when they compile a big kernel and load
the uImage at the default SDRAM + 2MB address as the kernel will
overwrite the uImage as it is being unpacked. Increase the default
load address so that we can load a 4MB kernel image without any
problems.

Wolfgang is right: It's not a good idea to set up default initial
ethernet addresses for a board, even though they belong to the local
range.
This will change the failure mode from "IT manager screams at you for
using duplicate ethernet addresses" to a nice error message explaining
that the ethernet address hasn't been set properly.

CFG_MEMTEST_START uses weird magic involving gd, which fails to
compile. Use hardcoded values instead (we actually know how much RAM
we have on board.)

Updates to atstk1002 U-Boot header file:
- Changed bootargs:
* Set the bootargs for at1002 to point to the SD-card partition instead
* ... of the boot flash.
* Removing the rootfstype since that argument are not needed.

This patch applies some clarifying comments to how the different
clocks are setup according to atstk1002.h Some of the previous
comments where stating wrongful information.

Include the imi, imls and jffs commands sets by default on ATSTK1000.
Also define CONFIG_BOOTARGS to something more useful, define
CONFIG_BOOTCOMMAND and enable autoboot by default.

Relocate the u-boot image into SDRAM like everyone else does. This
means that we can handle much larger .data and .bss than we used to.

Rewrite the resource management code (i.e. I/O memory, clock gating,
gpio) so it doesn't depend on any global state. This is necessary
because this code is heavily used before relocation to RAM, so we
can't write to any global variables.
As an added bonus, this makes u-boot's memory footprint a bit smaller,
although some functionality has been left out; all clocks are enabled
all the time, and there's no checking for gpio line conflicts.

Patch by Haavard Skinnemoen, 06 Sep 2006
This patch adds support for the ATSTK1000 with the ATSTK1002 CPU
daughterboard.
ATSTK1000 is a full-featured development board for AT32AP CPUs. It
has two ethernet ports, a high quality QVGA LCD panel, a loudspeaker,
and connectors for USART, PS/2, VGA, USB, MMC/SD cards and
CompactFlash cards. For more information, please see this page:
http://www.atmel.com/dyn/products/tools.asp?family_id=682
The ATSTK1002 is a daughterboard for the ATSTK1000 supporting the
AT32AP7000 chip.
