-/* STM Serial Memory Interface (SMI) controller is a SPI bus controller
- * specifically designed for SPI memories.
- * Only SPI "mode 3" (CPOL=1 and CPHA=1) is supported.
- * Two working modes are available:
- * - SW mode: the SPI is controlled by SW. Any custom commands can be sent
- *   on the bus.
- * - HW mode: the SPI but is under SMI control. Memory content is directly
- *   accessible in CPU memory space. CPU can read, write and execute memory
- *   content. */
-
-/* ATTENTION:
- * To have flash memory mapped in CPU memory space, the SMI controller
- * have to be in "HW mode". This requires following constraints:
- * 1) The command "reset init" have to initialize SMI controller and put
- *    it in HW mode;
- * 2) every command in this file have to return to prompt in HW mode. */
