Also, this API doesn't actually have anything to do with memory mapping.
It has to do with the de facto standard flash protocol. So I don't think
mmap belongs in the name; it should be

In addition to providing direct access to SPI bus, some spi controller
hardwares (like ti-qspi) provide special memory mapped port
to accesses SPI flash devices in order to increase read performance.
This means the controller can automatically send the SPI signals
required to read data from the
