- 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.

- 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.
