If you're going to revise this patch for the comment below, then I would
suggest removing the blank line before that if statement.

Do we need to add the following here:
#if !IS_ENABLED(CONFIG_OF)
static inline void register_trusted_foundations(...) {}
#endif
So that there is a dummy no-op function for the non-DT-support case? I
guess Tegra always has CONFIG_OF enabled so that call from
mach-tegra/common.c in patch 2 will never be an issue, but perhaps it
might if anyone else uses this?
