It is easy. Download the datasheet from their web site. Find out the
read/write/erase/id command set. If the command set is the same as
some previously implemented chip, just add a new entry in the
flashchips array in flash_rom.c with correct ID/NAME information and
point the "method" to the correct driver code. Otherwise, reuse the 
previously implemented driver which is closest to the new one.
