[U-Boot] [PATCH] Tegra: T30: Beaver board support.

[Tom Warren]

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.

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?
