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.
