Sixth attempt at the support for Trusted Foundations, which allows many Tegra-based (and quite possibly other) devices sold on the market to boot and be used with an upstream kernel. v5 did not receive many comments on the code itself, so I hope this means the patch set is converging well. Most remarks were about the lack of clarity about what Trusted Foundations is and how it fits with respect to SMC calling conventions and the PSCI standard (spoiler: it does not fit). Change against v5: - added a no-op of_register_trusted_foundations() for the case where neither Trusted Foundations nor device tree support are enabled - made it clear in the commit message and source file that TF does not follow the SMC calling convention, is totally independant of PSIC and only matters to devices that come with a bootloader that enables it.
