I initially thought the same, but unfortunately the load address is
not a parameter passed to the function, nor can it be extracted from
the spl_load_info structure.
Like you have probably discovered by now, the spl_load_fpga_image()
function was introduced to support the use case of  boards with
uninitialized DRAM, so the load address was not necessary.
On the other hand, the zynpl driver doesn't have functions to program
the FPGA by chunks, so I had to allocate memory.

Thanks,

Luis Araneda.
