However the following was added: "Only FVP platform will have SMP support and hence the secondary cpu definitions are not added to corstone1000.dtsi" Hugues pinged me in private to explain why it is done in that way and I asked him to add the reasoning in the commit message which he did but failed to capture in the v1->v2 changelog. I mentioned it in private again as he is new contributor to the kernel, I was less strict on him 😉. -- Regards, Sudeep
