I have three files which probably make sense to include the new flash part.
drivers/mtd/nand/nand_ids.c
./common/cmd_doc.c
./include/linux/mtd/nand_ids.h:

At this point, i do not understand the purpose of each and especially
how would the structure flash_id be populated from our data sheet for
the flash part we use
 "Samsung K9F1G08R0A".
I basically do not understand all the elements of the array
nand_flash_dev nand_flash_ids[] to be able to populate it correctly.
It would be great if you can throw some light on it or point me to
some relevant documentation.

Thanks in advance!
