Default xilinx board xupv2p xc2v30 software dev. doubt

I use the XUPV2P dev. board which contains XC2V30 chip. It contains
flash memory interface (ACE controller) and DDR Memory interface. I
thought of using the Flash as my boot loader to copy the image
(application) from PC and put it in RAM and execute from it. I'm using
my own controllers & processor.

Now since I 've some area unfilled, I feel, to synthesize ROM in that
and put the boot loader, which on reset, recieves the data from PC
(serial) and just put it in RAM and execute from the RAM.

or Is it better to program the flash offline, the image, copy them to
RAM on reset and execute from there. I feel running from FLASH is too
slow, as I can access only ACE controller, not the FLASH directly and
only 16x16 bits data buffer is there in ace controller, which makes
fetching the data from it takes more time.

Please comment anyother ways if anyone used xilinx flash card / ace
controller / DDR memory in the board. My image can be of 128Mb.
