The bulk of these changes are an effort to unify Tegra186 builds with builds of prior 64-bit Tegra generations. On top of that there are various improvements that allow data (such as the MAC address and boot arguments) to be passed through from early firmware to the kernel on boot.
The last two patches can be applied at a later time if the strndup() addition can't be merged along with the rest of the patches through the Tegra tree.
