The following series of patches prepares the ground to move the
remaining board configuration entries out of the Makefile into the
boards.cfg file, replacing multi-line scripts to fiddle with config.h
and config.mk files into simple, single-line entries.

[PATCH 1/3] Build: Add "board options" column to boards.cfg

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

    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

[PATCH 2/3] mkconfig: change CONFIG_MK_ prefix into plain CONFIG_

    mkconfig: change CONFIG_MK_ prefix into plain CONFIG_

    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.

[PATCH 3/3] Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE

    Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE

    The change is currently needed to be able to remove the board
    configuration scripting from the top level Makefile and replace it by
    a simple, table driven script.

    Moving this configuration setting into the "CONFIG_*" name space is
    also desirable because it is needed if we ever should move forward to
    a Kconfig driven configuration system.

Potential testers can find these (and some more experimental) commits
in the "Makefile-cleanup" branch in the u-boot-testing repository.


Best regards,
