The comment before the transmission loop in conjunction with the

"ethernet" alias does not exist, or if it points to a device tree node
that doesn't exist, or if the device tree node that it points to does
not have a "local-mac-address" property or if the value is invalid, it
will fall back to the legacy mechanism of looking for the MAC address
stored in the "nvidia,ethernet-mac" or "nvidia,ether-mac" properties of
the "/chosen" node.
The MAC address is then written to the default Ethernet device for the
board (again identified by the "ethernet" alias) in U-Boot's control
DTB. This allows the device driver for that device to read the MAC

Tegra186 build are currently dealt with in very special ways, which is
because Tegra186 is fundamentally different in many respects. It is no
longer necessary to do many of the low-level programming because early
boot firmware will already have taken care of it.
Unfortunately, separating Tegra186 builds from the rest in this way
makes it difficult to share code with prior generations of Tegra. With
all of the low-level programming code behind Kconfig guards, the build
for Tegra186 can again be unified.
As a side-effect, and partial reason for this change, other Tegra SoC
generations can now make use of the code that deals with taking over a
boot from earlier bootloaders. This used to be nvtboot, but has been
replaced by cboot nowadays. Rename the files and functions related to
