Diskonchip millennium as a boot device?

[Deya]

Hi,
     I want to use diskonchip millenium plus as a boot
device. Mine is PXA255 ARM processor.
     If I have to use DOCMP instead of flash as boot
device, what code all do i need to code? 
     By the DOCMP datasheet, I need a IPL, SPL
code....Do I have to code it myself or is it the one
given by M-systems? What bootloader should I use to
load the linux OS? 
    Is the TrueFFS driver from M-systems is a must or
linux diver is sufficient?
