Just to add to the complexity: are you aware that the  parameter  RAM
relocation  may  be  different between 8xx processors? For example it
seems that on the 866 family  you  can  relocate  PRAM  even  without
loading any uCode by just writing the correct offset to (for example)
the spi_rpbase register.
