heh ... well ... not so fast please !
There is a non-negligible amount of work to have a fully functional
imx31 on DT.

Not working:
- USB  (chipidea driver sort of works, but the PHY is a complete mess).
- Camera
- SPI hardware chip select support
- pinmux support is totally absent

Currently, on imx31 we can boot on DT with (and only if the bootloader
does the pinmux for you):
- Watchdog
- Timer
- Uart

And I did not even had a look at the i2c, EMI, LCD and sound support.

So I hope imx31 platform boards can stay until the situation gets better.
