mkconfig: change CONFIG_MK_ prefix into plain CONFIG_

2010-10-18T20:01:21+00:00

When planning for more generalization and Makefile cleanup it became
obvious that the introduction of a separate CONFIG_MK_ name space for
config options that were set through scripting in the Makefile was
not a good idea.

Originally the idea was to provide a script-free approach to supply
configuration options - there was no real need for a separate name
space. But when we now convert the existing Makefile entries to make
use of this approach, it would mean that we have to touch a large
number of board config files and add #ifdef / #define sequences to
"convert" from the CONFIG_MK_ to the CONFIG_ name space.

It seems much cleaner to get rid of this somewhat arbitrary _MK
string now for the few boards that actually use it.

Build: Add "board options" column to boards.cfg

2010-10-18T19:58:59+00:00

There are some boards where it's currently not possible to detect all
board information at runtime, therefore a new column was added to
boards.cfg .

This column can contain multiple options: a board configuration name,
optionally followed by a colon (':') and a list of options, which are
separated by comma (',').

In case of simple options like '256M_U_BOOT', these expand to
"#define CONFIG_MK_256M_U_BOOT 1" in config.h . In case of
assignments like 'RAM=8192', these expand to "#define CONFIG_MK_RAM
8192" in config.h .

Example:

	FOO:HAS_BAR,BAZ=64

means:
	- the name of the board config file is include/configs/FOO.h
	- the generated file include/config.h will contain these
	  lines:

		#define CONFIG_HAS_BAR  1
		#define CONFIG_BAZ  64

Makefile/mkconfig: read simple board configurations from boards.cfg

2010-06-13T16:08:22+00:00

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 "-".

Makefile: simplify handling of build target names

2010-06-13T16:08:18+00:00

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.

Move architecture-specific includes to arch/$ARCH/include/asm

2010-04-13T07:13:12+00:00

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.

config_defaults.h: new header for common u-boot config defaults

2010-01-17T23:04:42+00:00

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.

mkconfig: deny messed up ARCH definition

2009-11-24T22:37:00+00:00

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.

mkconfig: Create board directory (CONFIG_BOARDDIR) in include/config.h

2009-11-02T15:29:03+00:00

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.

mkconfig: split the board make target to multiple config targets

2009-09-15T20:14:18+00:00

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.
