The problem I am seeing is that the bdi2000 cannot communicate with the PM828 if the HRW is not present in the flash device. I.e. you need u-boot.bin already loaded into flash in order to load u-boot.bin into flash!
This is normal; with an erased flash, the processor will read a HRCW which sets external bus arbitration and CPU core disabled - there is nothing left for the BDI to communicate with.
At the moment I can work around this problem by setting some jumpers on the board to remap CS0 to a PROM device containing u-boot, writing the HRW into flash, and returning the jumpers so that CS0 is mapped to the flash again. Unfortunately I will not be able to do this on our custom hardware as there will only be a flash device and no PROM.
Install a RCFG jumper... The PM82x modules have a RCFG jumper to bring up the CPU in internal default configuration.
