So you want to do something like:
fis write -b 0x00100000 -f 0x0020000 -l 0x1000
ie write the contents of RAM 0x0010000, length 0x1000 to flash address
0x00200000. This does not need a buffer.

Yes, and also an option to specify where in memory the block should be
placed, so you can put it into the external RAM if you want to.
