[U-Boot-Users] Linux Kernel Config 1.2 for u-boot?
Hi !
Wouldn't it be nice to port lkc-1.2 to u-boot? I know that OpenZaurus already uses the system and I liked it there.
Yesterday evening I downloaded lkc-1.2 and patched it a little bit so that it workes in the u-boot tree. "make xconfig" already works. However, the real work will be the config.in files.
When I, for example, look at include/configs/dnp1110.h then I see lot's of defines and comments. With lkc, this would be very different. We would have a config.in file (most probably more than one file) which defines what is definable and also contains the code. The default-configs for the the boards would be automatically done.
This would be a tremendous change of focus, but I guess it might be worth it. It would give much structure.
Wolfgang, should I send you my tools/lkc-1.2 part of u-boot?

Something like that would indeed be nice; it has always been one of the things I tried to keep in mind - the close resemblance of the U-Boot config variables to the naming convention as used in Linux is intended.

Right.

I looked into creating an old-style Linux "make menuconfig" setup some time ago, but quickly gave up when I saw which amount of effort was required.

Sure, why not? If it's not too big (limit is 40k) you can even post it to the list, so others can get check this, too. [Or I can put it on a FTP server, or even in the CVS.]
Best regards,

It's a little above 40 kB. So feel free to download
http://www.mn-logistik.de/unsupported/pxa250/u-boot-kconfig.tar.bz2
and extract it inside your u-boot dir. Then do the following
export QTDIR=/where/is/your/qt? make -C tools/kconfig tools/kconfig/qconf config.in
(this could be integrated into the makefiles, but for now I was lazy)
The result will be a .config file that one can include in Makefiles or C source code. Currently it is not included anywhere, it's just created. However, it should give you an idea on what would be possible, even with the simple "config.in" files that I made.
However, lkc can ONLY handle variables with CONFIG_ at the beginning. Therefore I propose that --- on the long run --- some CFG_ variables get renamed to CONFIG_. For example, it would be very nice if one would have the available-command selection in "make xconfig"/"make menuconfig".
