If it's just about reading a file from usb and writing it to flash, you
might want to have a look at filo. It should be easy to integrate the
functionality of flash_rom into it, so you don't need a full blown linux
system in flash. 
Otherwise it is very much dependent on your flash size whether you can
fit Linux in there or not. 512k _might_ be enough if you really squeeze,
but unlikely.
