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