[U-Boot] [PATCH v4 00/19] ARM: tegra: Miscellaneous improvements

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

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.
