fpga: Change default burst for xilinx ips #34

Open CyrilKoe opened 1 month ago

CyrilKoe commented 1 month ago

When using certain Xilinx IPs, the burst type FIXED is not supported. In practice, they are not used (len=0) anyways.

AXI SmartConnect product guide (PG247):

SmartConnect does not support FIXED type bursts. Any FIXED burst transaction received at the SmartConnect SI is blocked and a DECERR response is returned to the master.
