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

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