flash programming STI 5.5.1.4 DCU3

##
## The c200 emulator ip address can be changed from the default by 
## defining the cl symbol c200_emul_ip_addr on the st20run command line.
## Similarly the JEI tckdiv can be changed by defining the cl symbol
## tckdiv. For example:
##  st20run -t c200_emul -define tckdiv=256 -define c200_emul_ip_addr=100 hello.lku
##
c200_rom_addr = 0x40000000
c200_rom_size = (512*K)

c200_external_addr = (c200_rom_addr + c200_rom_size)
c200_external_size = ((4*M) - c200_rom_size)

proc c200_emul_map {

  ## define memory segment FLASH as ROM to linker, but as RAM to
  ## st20run/st20sim so they can write romimage into FLASH
  ##
  if ((clsymbol alias) == 3) {
    ## only the linker has alias built in
    rom_type = "ROM"
  } else {

  ## For the emulator the top of memory ROM is mapped into FLASH as only the
  ## bits 0x003fffff are significant in an address.
  ## Do not use ROM1 segment as it is only intended as a placeholder
  ##
