| 5 | Broadcom home routers contain flash partition called "nvram" with all |
| 6 | important hardware configuration as well as some minor user setup. |
| 7 | NVRAM partition contains a text-like data representing name=value |
| 8 | pairs. |
| 9 | This driver provides an easy way to get value of requested parameter. |
| 10 | It simply reads content of NVRAM and parses it. It doesn't control any |
| 11 | hardware part itself. |

| 18 | Broadcom devices store configuration data in SPROM. Accessing it is |
| 19 | specific to the bus host type, e.g. PCI(e) devices have it mapped in |
| 20 | a PCI BAR. |
| 21 | In case of SoC devices SPROM content is stored on a flash used by |
| 22 | bootloader firmware CFE. This driver provides method to ssb and bcma |
| 23 | drivers to read SPROM on SoC. |
