- * 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.

- * TODO
- * Use Primary Extended Query table (PRI) and Alternate Algorithm Query Table (ALT) to determine if protection is available
- * Add support for other command sets Use the PRI and ALT to determine command set
- * Verify erase and program timeouts.
