I don't know, to which USART the output goes. I guess you assume, my
"GPIO debugging" was to meassure the pulses on the USART pins. But no, my
GPIO debugging was as follows:
-set gpio pin with led attached
-send characters by puts() (wherever it goes) ;-)
-reset gpio pin
-measure time between high- and low- rising edge on gpio pin
-calculate baudrate

(on DBGU pin, there is no pulse at all past starting U-Boot)

Yes, according to datasheet, Debug Unit Control Register (DBGU_CR) is
located at 0xFFFFEE00.
And in at91sam9263.h is defined:
#define ATMEL_BASE_DBGU         0xffffee00

Yes, I'm using the driver with your changes from 2010-11-03 16:32:56
