If enabled, SPI 0 is reserved for accessing the SPI flash ROM and a
|
|
|
|
|
driver interface won't be instantiated for SPI 0.

Beware disabling this option on HiFive 1! The SPI flash ROM is where the
|
|
|
|
|
program is stored, and if this driver initializes the interface for
|
|
|
|
|
peripheral control the FE310 will crash on boot.
