The kernel will read the number of cores from the fuse and will bring-up the correct number of CPU cores. Other i.MX6Solo boards do not do this either.
I would argue the above is more accurate, since this thing is supposed to be populated only with MX6 Solo. Even better might be to /delete-node/ cpu@1 in fact. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
