Thanks, I have queued this up for v4.5.
Thanks. May I ask if CPU hotplug is known to work?
I didn't test that.
As a follow-up I am wondering if you subsequently observed CPU hotplug
working. My recent testing on v4.5 indicates that it isn't working in my
environment. It would be quite valuable to know if it has ever been known
to work.
Also, which version
of the boot loader stack is required?
Yes. CPUHotplug will be supported in boot loader stack released by Dec
2015 and later.
I've the U-Boot / boot loader stack from BSP v3.0.2 on the board. I haven't
tested v3.0.3, yet.
