Merge tag 'tegra-for-3.10-multiplatform' of git://git.kernel.org/pub/…

…scm/linux/kernel/git/swarren/linux-tegra into next/multiplatform From Stephen Warren <[email protected]>: ARM: tegra: multi-platform conversion This branch converts Tegra to support multi-platform/single-zImage. One header is made accessible to drivers. The earlyprintk implementation is moved to the multi-platform location. Some Kconfig changes are made to enable multi-platform. Some dead files are deleted. The APIs exposed in the now-global tegra-powergate.h should be replaced with standard reset and power domain APIs in the future. This branch is based on (part of) the previous soc pull request. * tag 'tegra-for-3.10-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: ARM: tegra: convert to multi-platform ARM: tegra: move <mach/powergate.h> to <linux/tegra-powergate.h> Signed-off-by: Arnd Bergmann <[email protected]>
