for the Alphas long ago I modified flash_rom as follows:

flash_rom e <start block #> <length in blocks>

Erase the blocks

flash_rom r <start block #> <length in blocks>

read the blocks

flash_rom p <file name> <start block #>

program with file name starting at start block #. Program up to the limit
of the file size or the flash size, whichever is small. This was for 
partial programming.

flash_rom s <start block #> <lenght in blocks>

program using stdin as the data, starting at start block # and for length
blocks OR eof on stdin, whichever was smaller.

This was pretty handy for the DS10, which had 2 MB of flash in 64KB 
blocks, and had areas of flash we could not rewrite.

maybe we need this for the general case?

yes, that's true. It will not work with flexible parts.
