2 | /* JEDEC Flash Interface. | ||
3 | * This is an older type of interface for self programming flash. It is | ||
4 | * commonly use in older AMD chips and is obsolete compared with CFI. | ||
5 | * It is called JEDEC because the JEDEC association distributes the ID codes | ||
6 | * for the chips. | ||
7 | * | ||
8 | * See the AMD flash databook for information on how to operate the interface. | ||
