Instead of adding explicit build rules for each and every board to the
top level Makefile (which makes it grow and grow), we now provide a
simple default rule and extend the "mkconfig" script to read board
configurations from a plain text file (table), "boards.cfg".
For simple boards it is now sufficient to add a single line of text to
the "boards.cfg" file, no changes to the top level Makefile are needed
any more.
To make the table better readable, change the notation for unused
fields from "NULL" into "-".

Instead of stripping the "_config" part from the make target names in
each call of the "mkconfig" script let this script strip the string.
This prepares the ground for forther simplification of the top level
Makefile.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

There are a bunch of features in U-Boot that we want to enable by default,
and it's best if we centralize them in one place rather than updating all
the board files out there.

Refuse to setup a platform if the command line ARCH= is not the same
as the one required for the board. This prevents any user with
prehistoric aliases from messing up their builds.

This patch extends the mkconfig script to automatically create a define
for the board directory in include/config.h:
#define CONFIG_BOARDDIR board/amcc/canyonlands
This is needed for the upcoming PPC4xx linker script consolidation,
where the PPC440 platforms need to include a board specific file in
the common linker script.

To simplify the top level makefile it useful to be able to parse
the top level makefile target to multiple individual target, then
put them to the config.h, leave the board config file to handle
the different targets.
Note that this method uses the '_'(underline) as the delimiter when
splits the board make target.

Then we can handle different config targets in the board file, which
simplifies the top level Makefile for boards that have multiple
config targets.

We have common defines that we duplicate in various ways. Having an
arch specific config.h gives us a common location for those defines.
Eventually we should be able to replace this when we have proper
Kconfig support.

Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
- make highboot configurations use environment at high end, too,
to avoid flash fragmentation
- always use redundand environment
- don't enable video code for modules without graphics controller
- provide useful (though different) mtdparts settings
- get rid of CONFIG_CS_AUTOCONF which was always set anyway
* Extend mkconfig tool to print more useful target name
- Introducing the concept of SoCs "./cpu/$(CPU)/$(SOC)"
- creating subdirs for SoCs ./cpu/arm920t/imx and ./cpu/arm920t/s3c24x0
- moving SoC specific code out of cpu/arm920t/ into cpu/arm920t/$(SOC)/
- moving drivers/s3c24x0_i2c.c and drivers/serial_imx.c out of drivers/
into cpu/arm920t/$(SOC)/
* Patch by Murray Jensen, 24 Jun 2003:
- make sure to use only U-boot provided header files
- fix problems with ".rodata.str1.4" section as used by GCC-3.x
