Hello, This series of patches brings initial support of Trusted Foundations to Tegra30, that is to the consumer-grade Tegra30 devices which do not allow to easily replace the proprietary bootloader. Support is initial because this series implements only a proper CPU boot-up (main + secondary cores) and a basic L2 cache maintenance that is done using the TF firmware. Suspend-resume support is missing yet as I couldn't get it to work (CPU hangs on resume from suspend after awhile and seems that is related to inappropriately done cache maintenance during of suspend-resume using the firmware), it is work-in-progress for now. This patchset is partially based on the work done by Michał Mirosław [0]. Please review, thanks.
