U-boot for Nios II on the 10m50 dev board is not functioning. The serial terminal prints nothing upon booting up. The u-boot image is loaded via GDB/JTAG to the FPGA on-chip RAM.
Bisect activities were carried and discovered that the change from using dm_scan_fdt_node to dm_scan_fdt_dev in the simple_bus.c. This leads to suspecting the 10m50_devboard.dts need update to include "u-boot,dm-pre-reloc".
u-boot,dm-pre-reloc has to be present in each item of the DT path leading to the node where you need it.
