if you have systemace based board then you can load the image from CF
also
it does use the JTAG debug interface for software loading, this
however only
works if you load from ace file, if you load the bit file over jtag
with debug cable
the soft would not get initialized

otherwise creating an custom ram loader is one ore more MAN-WEEK of
work
this is the time YOU have to spend doing real work, asking for help
doesnt
count as work done
