No, I want to do something like this:

load -r -f 0xa0000000 -m ymodem

I want to load a program directly into the flash memory via
a serial line.
For this operation Redboot uses the flash_load_write()-function,
which saves the block to a buffer in RAM.

Using the "fis write"-command doesn't solve my problem.
On the one hand I have to load the application into RAM
first, but I can't be sure that I have enough RAM for this.
And on the other hand I can only write data to the beginning 
of a block and the whole block will be erased. So even if I want
to write only a part of the block the whole old data in the block
will be deleted.

Thanks
