This set mainly added DeviceTree based CPU probe support and reworked topology handling for MIPS. In order to prepare for pure DeviceTree boot for Loongson64. It can also convinient Yanjie's Inegnic jz4780/X2000 SMP/SMT support.
I've done build test for bmips, nlm, ip27 and boot test for malta with 34Kf, I6400 in QEMU, Loongson64 on a Loongson-3B1500 real machine.
Thanks.
