• • This file implements a Common Flash Interface (CFI) driver for

U-Boot.

• • The width of the port and the width of the chips are determined at

initialization.

• • These widths are used to calculate the address for access CFI data

structures.

• • It has been tested on an Intel Strataflash implementation and AMD

29F016D.

command set
