More multiplatform enablement for ARM platforms. The ones converted in this branch are: - bcm2835 - cns3xxx - sirf - nomadik - msx - spear - tegra - ux500 We're getting close to having most of them converted! One of the larger platforms remaining is Samsung Exynos, and there are a bunch of supporting patches in this merge window for it. There was a patch in this branch to a early version of multiplatform conversion, but it ended up being reverted due to need of more bake time. The revert commit is part of the branch since it would have required rebasing multiple dependent branches and they were stable by then. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJRgg99AAoJEIwa5zzehBx3n78P/j0w/8v+F4dM29ba5M/tqbFI e3wpeFykZ/HJH+FFIEYfIablpfHsLB0LEMh0dZmwHESFC6eR0RfGL2jOkpfcH9Ne 7B/JIFN4l1iwqqKCXf+QbYL6e8YFxlJkg6BIB4KhNgliQoO/ASP/8EbcgROYuxmN KPVdw9laUCCvb5Ogh2NWVAkBHhVGAEiqK20r4TQz8alI8RUmMleWM3o+wLBWVhOO d3gtYSfuFSbrJfbpKSdycLizoV/NekdOC1A9Ov9YuOdw8DzNbrThCRQtu0tIUgxN JjfnGlEJLsJS9SESfr8SYWxTuhe/lB2dGqjQPvRtl2HGBhbtTlnWfQ0k2ZHdeJuD J50SLrGA2gN9E5PlHJXjYk8uhhGIq8bNTJ//CtDkfKTq1D7PuHVEpEctsaz3BBbM U+x9zP2v4FB+yrZu8w+gkQY/wDgHsxj08mT6BK0+l8ePdyQV22CvwmM5XlJFI03x 5J0nLYiYfef+ZN9rGgVrQbn+yv+IEkE4DmeiscjeVJE5LVdVrDpYGfx7UA7V0UA7 i3KRVpNKuy1v7GJDnKlEBPkmB+vgXTRXUPDVCuC4n0Hi5PYj4es1gY6AoXGF90wm vtKxGr/2XDLP7Ro+m0OXMttSgQShnmbrbOngfkWcFwUmG7cB3SSUUOGKM+2LNnXM MJTqVhPjkZ2GYBi/J6S/ =4hSo -----END PGP SIGNATURE----- Merge tag 'multiplatform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform updates from Olof Johansson: "More multiplatform enablement for ARM platforms.
