the bootloader was putted at 0x1F000 with following LDFLAG in Makefile:
   LDFLAGS += -Wl,--section-start=.text=0x1F000

The Bootloader program works fine. I could read and write to UART0 
interface and do read options to flash sections.

I call the function with the address 0x0000.

Here are my fuse settings:
   lfuse = 0xFF
   hfuse = 0x91
   efuse = 0xFE
