IPMI channels are configured with a JSON file that lives in 
/usr/share/ipmi-providers/channel_config.json on the BMC. The default 
file in yocto-land lives at 
meta-phosphor/recipes-phosphor/ipmi/phosphor-ipmi-config/channel_config.json 
and can be overridden with bbappend.

Making your own config is as easy as overriding the default with 
bitbake.

I don't recall if there was an email, but several months back, there 
were user/channel config reviews out that slowly got merged in.
