1 | config BCM47XX_NVRAM |
2 | bool "Broadcom NVRAM driver" | |
3 | depends on BCM47XX || ARCH_BCM_5301X | |
4 | help | |
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. | |

13 | config BCM47XX_SPROM | |
14 | bool "Broadcom SPROM driver" | |
15 | depends on BCM47XX_NVRAM | |
16 | help | |
17 | Broadcom devices store configuration data in SPROM. Accessing it is | |
18 | specific to the bus host type, e.g. PCI(e) devices have it mapped in | |
19 | a PCI BAR. | |
20 | In case of SoC devices SPROM content is stored on a flash used by | |
21 | bootloader firmware CFE. This driver provides method to ssb and bcma | |
22 | drivers to read SPROM on SoC. |
