Yeah ;) I'll give it a try soon and see how it works out.

 Thomas> Ah, I'm interested in how you would do that. Currently, what the

I was thinking that we maybe could (ab)use the KCONFIG_ALLCONFIG support
stuff for it. From linux/Documentation/kbuild/kconfig.txt:

The allyesconfig/allmodconfig/allnoconfig/randconfig variants can
also use the environment variable KCONFIG_ALLCONFIG as a flag or a
filename that contains config symbols that the user requires to be
set to a specific value.

But I haven't looked at it in detail yet.

Yes, that's the step I think we could automate when the toolchain comes
from buildroot.
