+Some devices form STMicroelectronics (e.g. STR75x MCU family,
+SPEAr MPU family) include a proprietary
+``Serial Memory Interface'' (SMI) controller able to drive external
+SPI flash devices.
+Depending on specific device and board configuration, up to 4 external
+flash devices can be connected.
+
+SMI makes the flash content directly accessible in the CPU address
+space; each external device is mapped in a memory bank.
+CPU can directly read data, execute code and boot from SMI banks.
+Normal OpenOCD commands like @command{mdw} can be used to display
+the flash content.
+
+The setup command only requires the @var{base} parameter in order
+to identify the memory bank.
+All other parameters are ignored. Additional information, like
+flash size, are detected automatically.
