Merge tag 'realview-multiplatform-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/multiplatform
Pull "Multiplatform support for the RealView" from Linus Walleij: Here is the result of my application of the second part of Arnds patchset, actually enabling multiplatform and getting the RealView off the ground as a multiplatform target. It is dependent on an outstanding patch to the irqchips tree bumping the number of GICs to 2 for the RealView platform. I cannot say I will be sleepless if these go in side by side: each branch will compile but will not boot until both trees have been pulled hurting bisectability a bit. - Tested on the ARM PB11MPCore - Tested with boardfile boot - Tested with DeviceTree boot * tag 'realview-multiplatform-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator: ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform
