[U-Boot] [PATCH] Tegra: T30: Beaver board support.
Beaver is a Tegra30 board that is nearly 100% compatible w/Cardhu. Add a Beaver build so it can begin to be differentiated, if need be.

OK, I assume cardhu and beaver dts files differ, right? If so, maybe we can find a smaller way to just say we have N boards that use a different dts, but that's it?

I think you can do that just be modifying boards.cfg; n lines with the same content except for the name in the first column, e.g.:
snow arm armv7 smdk5250 samsung exynos smdk5250 arm armv7 smdk5250 samsung exynos
You can also add an extra column with options if needed, although I imagine the makefiles can see the value of the first column to e.g. select different .dts files?
Perhaps we should do the same for Seaboard/Ventana too.

Right now, they only differ in the 'model' and 'compatible' fields
(because of the name change), and max memory (Beaver has more).
At some point, it may be more than just a DTS difference, though.

OK. And this is something I'm struggling with and thinking about for am335x, we want to make it easy to re-use SoC-specific bits (say memory controller) as well as likely used things (say ethernet). Or are you not quite at the point of number of boards to be able to say whats likely reused but not SoC specific?
