The removable device is a good idea. Once you get the process down,
you should be able to build an image, program it into the part, install the
part on the board and boot it. Make that image a serial loader that can
program the other flash part if you must, or just run from the EEPROM
during development.
I agree with Jerry, JTAG is horribly slow and your time would be spent
more wisely on a serial loader or the end application. I have written a
couple of JTAG loaders that operate on the PC serial port using a
Xilinx Parallel III cable. The last one requried 12 minutes to program
40Kb into flash. We use that as a last resort to load a blank board
with a serial loader.
