Hi Wolfram,

Nice to hear from you here ;)

As of 4e410f3e68280 PBL is always used on AT91.

I have no idea how the SDRAM setup is done on the USB-A9G20. There seems
to be SDRAM setup code for the USB-A9263, but not for the USB-A9G20. Is
there some AT91Bootstrap required?

Anyway, what's really missing is DT support. I scribbled a patch to get
you started in case you are motivated. Basically it's: Compile in the
device tree, throw away all the device registration from the board code,
see where it gets you and fix the fallout ;)

Regards,
 Sascha
