Subject[PATCH v1 0/5] Initial support of Trusted Foundations on Tegra30
Date
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.
