Hi Vasyl,

Without armv8_setup_psci register VBAR_EL3 is not set up property which makes SMC calls jump to invalid location.
smp_kick_all_cpus is required to make slave cpus leave gic_wait_for_interrupt. Without this they will never pursue booting process.
This implementation is very similiar to what is done in boot_jump_linux in arch/arm/lib/bootm.c file.
Tested on VxWorks 7 release SR0520 2017-12-08.
On what board?
As I mentioned before, why do you want to use 'bootvx' to boot a VxWorks 7 kernel? I believe VxWorks 7 ARM kernel is loaded via 'bootm'. See doc/README.vxworks.

What about ARMv8 32-bit? What about ARMv7? Should we call smp_kick_all_cpus() for ARMv7 as well? Seems to me the logic of #ifdefs here needs to be tuned.
