| H A D | spi-nor.rst | 2 SPI NOR framework
5 Part I - Why do we need this framework?
6 ---------------------------------------
8 SPI bus controllers (drivers/spi/) only deal with streams of bytes; the bus
11 arbitrary streams of bytes, but rather are designed specifically for SPI NOR.
13 In particular, Freescale's QuadSPI controller must know the NOR commands to
14 find the right LUT sequence. Unfortunately, the SPI subsystem has no notion of
15 opcodes, addresses, or data payloads; a SPI controller simply knows to send or
18 details of the SPI NOR protocol.
20 Part II - How does the framework work?
