| 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. |
