[U-Boot] [PATCH 0/20] tegra: Expand Nyan-big support

[Simon Glass]

This series expands Nyan-big support:

- Enable Chrome OS EC, so that the keyboard works
- Add some extra clock and pre-kernel init required for reliable operation
- Add Chrome OS environment variables, including 'run nvboot' to allow
booting Chrome OS more easily

Still missing are audio and USB.
