Dear Albert ARIBAUD,

Thanks for the proposal. Unfortunately, it turns out that the Orion ED
Mini V2 is one of the two boards I already have, so I can test on this
one. However, it would definitely be useful to have your testing and
feedback.

I've posted the patch series on LAKML just a few hours ago, you can
also grab the code from:

  https://github.com/MISL-EBU-System-SW/mainline-public/tree/3.15/orion

In this branch, Orion ED Mini v2 is fully converted to the Device Tree.

For now, I'm using the U-Boot included with the boards, so it does not
have FDT support, which means I'm using appended DTBs.

Do you know if UART booting works for Orion boards? If not, what is the
recovery mechanism if you screw up while reflashing U-Boot?

Thanks!
