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
