Kconfig debug help

I'm trying to debug some Kconfig problems and am looking for a way to
get more debug output.

 

I have used KBUILD_VERBOSE=1 on the command line and it didn't help
much.

 

I'm seeing an issue with creating a new defconfig file for a board.  I
get the .config created, then copy it to a defconfig, and then it
doesn't do anything when I run make with the defconfig file.  

 

Thanks for any help,

John

Yeah, I hit that myself this weekend.  It's a bug in the Kconfig area.
It's 1/2 fixed in the latest Linus and powerpc trees.

Thanks Josh, I just came to the conclusion it was busted somehow in the
mainline after repeating it there.

    kconfig: always write out .config
    
    Always write out .config also in the case where config
    did not change.
