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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQaO7aAAoJEIwa5zzehBx3bUIP/02U8PhkHJJrrowyIsWRBOql 7LPJ53PRRgrpBdmEGzFD3TO3zaNyrjQRbYgNDvzHMO6NAMNvdRFouuWYjO11/tuB i32zssXCC+eUOEgbAo/U/lYq+UOvqw9gv6mU+3+i3OcGEhdKOaoT/DSLPQC4hoDm 222TeLfFB3HJXu5n720dEQ9V3fO6TS1+bbh8TU3cjHqzceXsOrffZqOA5CQxUcRr KWwOjA0nALDwWcqgv45GJNwY3GTyAQ/hPMQavnuWK0voJ+qUYk5HftKocAK7C+py 0T0OFOAHTwtyhvzJBxLC84M6Ox465BYXyeNjIB+2nG/Um9+mDoP0dnWpGy4c7DMU P5hyqbeLGeqjUXQuYtRmgMMc3UeHKoUGAfXW9eMsjLa6/M4NLGv//7E7LbZPpgMZ obkjwuesmcaYn/FRyj/yFmC35YlF4oCLziVzEtURZw3eKHHSUlhkTDSMNnkcZ0kZ Vv7kFxnD2Y46ixiwSJv30ErQnVkgI3MdqDlDxkE8r5+phYuK4gCrNaJtiwRh/oNw cFhpPxKuA0sJ9b6YRTzjC45eT/XZomEEr/uifCFeRNaCquyjYP00Mm8F0flSqwx9 zi+emzPAwNmk1bvxMUM/idGnaj0V4p+BAYUAvkbSoqU1p1flzyhU88fGTSIyKOt6 K5TCDS2v5hrVykK9TDwl =Tc6y -----END PGP SIGNATURE----- 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.
