I did a "make kernel_oldconfig" to refresh the configuration. This was
either not done when this configuration was added, the generic
configuration changed or some new Kconfig options were added in the
stable kernel.

They are automatically set because CONFIG_CAVIUM_OCTEON_SOC selects

The architecture supports them, they are automatically selected.

Yes I agree with you, when I looked at the kernel configuration of the
at91 target for example there were many problems in there. It is also
not really documented on how to do it correctly.

Only defining the options which are really needed and using the
defconfig for all of the others could also be an option, but I think we
would miss to much stuff.
