| This option enables the SoC Controller Driver which verifies | |
| LiteX CSR access and provides common litex_[read|write]* | |
| accessors. | |

| 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. | |
