I think the problem here is too much use of select, for things that
should instead be in the defconfig.
The patch below results in the same result for make
44x/akebono_defconfig. Does it fix the original issue?
We don't need to add ETHERNET or NET_VENDOR_IBM to the defconfig because
they're both default y.
cheers

Sure. I thought that lots of what was already there
should be in the defconfig. I was just going with the flow.
Thanks for fixing it.

Hi Michael,
Sorry for the delay.
Changing the akebono_defconfig doesn't cause the missing symbols
to be set -- the defconfig is not being used here.
I guess that if you have users who set CONFIG_AKEBONO and expect
it to build cleanly, you will need something like my patch or the
patch that Florian just posted.
Changing the akebono_defconfig also would not help 'make randconfig'
builds to build cleanly if they had happened to enable AKEBONO.

Yep, but that's OK. None of those selected symbols are hard dependencies
of AKEBONO, they're just things you probably want in your kernel to
actually boot on an akebono board.

It will build cleanly, it just won't necessarily boot on a real board.
Users who enable AKEBONO manually need to know what they're doing, or
they should just use the defconfig.

Changing the defconfig doesn't help randconfig, but dropping the selects
does.
Anyway I'll send a proper version of my patch, which I'm pretty
confident will fix all the issues.

Yep, but that's OK. None of those selected symbols are hard dependencies
of AKEBONO, they're just things you probably want in your kernel to
actually boot on an akebono board.

It will build cleanly, it just won't necessarily boot on a real board.
Users who enable AKEBONO manually need to know what they're doing, or
they should just use the defconfig.

Changing the defconfig doesn't help randconfig, but dropping the selects
does.
Anyway I'll send a proper version of my patch, which I'm pretty
confident will fix all the issues.
