Merge tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc multiplatform enablement from Olof Johansson:
"This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot
of driver/platform shared definitions have gone, such as platform
data structures. They now need to move out to a common location
instead, and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move
and once it settles in, we should be good for quite a while. Sorry
for the overhead."
Fix conflicts as per Olof.
