/* JEDEC Flash Interface.
* This is an older type of interface for self programming flash. It is
* commonly use in older AMD chips and is obsolete compared with CFI.
* It is called JEDEC because the JEDEC association distributes the ID codes
* for the chips.
*
* See the AMD flash databook for information on how to operate the interface.
