7title: NXP SPI Flash Interface (SPIFI)
8
9description:
10  NXP SPIFI is a specialized SPI interface for serial Flash devices.
11  It supports one Flash device with 1-, 2- and 4-bits width in SPI
12  mode 0 or 3. The controller operates in either command or memory
13  mode. In memory mode the Flash is accessible from the CPU as
14  normal memory.
