Thank you for the pointer. I might have seen that before, but never
investigated why it is not working for me.

None of the LS1012A board RCW builds result in a file name with "qspiboot"
in them. Therefore, this step is not done for the RCW files generated for
these boards.

I see that many other LS1 boards get "qspiboot" in the file name (ls1021a*,
ls1043a*, ls1046a*) but I have not figured out how/why.

The ls1012a* boards all have a qspi_endianess.rcw snippet with the same
commands:
      .pbi
      write 0x550000, 0x000f400c
      .end

Is this supposed to take the place of the byte_swap script?
