;   This code is intended to be used with hardware probe to flash NOR
;   flash memory. It comprises two part - first hardware initialization
;   (we need initialize SDRAM controler) and second - NOR flash erase
;   and programming. It is assumed that user will download data to SDRAM
;   between first and second step.
