2020-05-18common: Drop net.h from common headerSimon Glass
Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-06-05ARM: tegra: Implement cboot_get_ethaddr()Thierry Reding
This function will attempt to look up an Ethernet address in the DTB that was passed in from cboot. It does so by first trying to locate the default Ethernet device for the board (identified by the "ethernet" alias) and if found, reads the "local-mac-address" property. If 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 address from the standard location in device tree.

2019-06-05ARM: tegra: Unify Tegra186 buildsThierry Reding
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 This used to be nvtboot, but has been replaced by cboot nowadays.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 this to avoid confusion. The implemented protocols are unchanged.
