This option enables the SoC Controller Driver which verifies |

LiteX CSR access and provides common litex_[read|write]* |
|
accessors. |

All drivers that use functions from litex.h must depend on |

LITEX. |

LiteX MMIO registers (referred to as Configuration and Status |
|
registers, or CSRs) are spread across adjacent 8- or 32-bit |
|
subregisters, located at 32-bit aligned MMIO addresses. Use |
|
this to select the appropriate size (1 or 4 bytes) matching |
|
your particular LiteX build. |
