From: Uwe Kleine-König @ 2016-01-20  7:47 UTC (permalink / raw)
  To: barebox

Currently only second stage booting from the vendor U-Boot is tested. I
don't want to flash barebox into NAND yet because UART-booting for
recovery doesn't work for me.

Working so far are:

 - UART
 - networking
 - nand flash
