[PATCH 0/5] ARM: at91: add first DT support for Calao usb/tny boards

[Ahmad Fatoum]

We have a lot of defconfigs for ARM9 AT91 boards, that we want to get
rid off after migrating the boards to at91_multi_defconfig.

Thanks to a temporarily donated Calao USB-A9G20 by Wolfram, we start by
switching the Calao boards to DT.

This is not yet a complete replacement:

  - We use the legacy NAND driver instead of the newly backported driver
    that Linux uses with the hardware, presumably without issues

  - OHCI hangs during probe, so it's disabled for now

  - A barebox with comparative functionality to the non-DT version
    exceeds the 256K partition size

These can be resolved separately though, so add here first DT support.
