Small drive-by comment.
This is quite different from the Device Tree in the Linux kernel tree,
and it hasn't been changed a lot in the last few years.
1) Is there any reason for not sync'ing with upstream Linux kernel
instead of having our own Device Tree?
2) Do you think it'd be possible to use OF_UPSTREAM instead which would
make it possible to use the device tree from the Linux kernel (it is
available in dts/upstream/src/arm/nvidia/tegra20-acer-a500-picasso.dts)?
I don't think it's a straightforward thing to do but haven't do it
myself, so no clue what's required and the amount of effort to put into
it. The benefit is that fixes to the DT will eventually make it to
U-Boot as well and we hopefully lower the maintenance burden on U-Boot
contributors/maintainers.
Cheers,
Quentin
