ARM: arm-soc: Merge branch 'next/smp' into next/soc2
Merging in the smp-on-socfpga branch into soc2 since the topics are similar
and it's a short branch in the first place.
* next/smp:
ARM: socfpga: mark secondary_trampoline as cpuinit
socfpga: map uart into virtual address space so that early_printk() works
ARM: socfpga: fix build break for allyesconfig
ARM: socfpga: Enable SMP for socfpga
