Since there are a large number of them, put them in a separate file to include. On models with only 1 GB of memory, only two memory channels are used, and on models with 2 GB of memory, four memory channels are used. The "apple,always-on" property of the extra memory channel power domains (ps_dcs2, ps_dcs3) will be removed by loader on models with 1 GB of memory. The amount of memory depends on the storage configuration of the Mac.
