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 <swarren@wwwdotorg.org>:
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.
