Thierry, since you're most familiar with display support and IIRC have
worked on this in U-Boot too, perhaps you could review this series? Let
me know if you need me to forward the emails to you.

Which boards in particular? If this is just other Tegra20 boards and
simply because you haven't copied the relevant DTs from the kernel
and/or made updates to any U-Boot defconfigs and/or config headers,
can't you do that mechanically too? Sure you'll need other people to
test boards you don't have, but IIUC the source changes are mechanical.
If it's non-Tegra20 boards, can you expand on the cause of the breakage?
