Fine to hear that you guys work on it ;-) I asked about two week ago on this list, if there is any on-going project. And as I didn't get any answer, I simply did my own experiments.
I ported kconfig and modified the U-Boot sources to use it. Most time I spent on just grouping options in a kconfig tree. I tried to apply my changes in a way compatible with the existing U-Boot sources. You can now use the old, the new or a mixture of both system (strongly discouraged).
My own U-Boot target is using kconfig already, and porting further platforms from the old to the new system should be straight forward - just start 'make menuconfig' and answer all question from top down (No it's nmot complete yet... but easy to extend now.) And you can always switch back in case it doesn't work.
While doing these modification I found many 'problems' with the existing build system, which either need to be worked around (CFG_ style defines) or to be fixed the real way. There are also many things which could be simplified with kconfig. Although this will take some time, it is possible to migrate the current U-Boot configuration this way.
The other way is to recreate a new sourctree and throw away everything no longer needed, reorganize structure and so on - much easier. And after my review of the U-Boot source I tend to use the second way. But this would be basically a new project, and merging changes between both projects might become more difficult. Something I tried to avoid
From the list of features I got the impression, that u2boot used the
second way and is mostly done. And the described features and changes should solve most or all of the issues I found.
So when can we access a first draft of u-boot-ng? I would like to have a look on it. Maybe there is some way to allow users of u-boot to migrate smoothly to the new system.
It would be a pitty to have two bootloader projects covering the same targets. People would start to work on the one or other project, instead of focusing their efforts on a single solution.
