If such documentation exists, I don't know about it. Most people either use the
shotgun approach and enable everything the way distro does. If you build a lot
of kernels, and do not want to waste time on things you will never use, then a
minimum configuration is created, and then one looks carefully at the things
that don't work. In this case, the key was knowing that recent Broadcom devices
need bcma to work, while older ones need ssb.
The tough part is when a particular distro depends on an unusual combination of
configuration parameters for their kernel to function. Linus Torvalds has just
started a conversation on this issue. See the thread at
https://groups.google.com/forum/?fromgroups#!msg/fa.linux.kernel/EqysPjaJGDU/oDG2WXqokNoJ.
