MIPS: BCM47xx: Move NVRAM driver to the drivers/firmware/
After Broadcom switched from MIPS to ARM for their home routers we need to have NVRAM driver in some common place (not arch/mips/). As explained in Kconfig, this driver is responsible for parsing SoC configuration data that is passed to the kernel in flash from the bootloader firmware called "CFE". We were thinking about putting it in bus directory, however there are two possible buses for MIPS: drivers/ssb/ and drivers/bcma/. So this won't fit there and this is why I would like to move this driver to the drivers/firmware/.

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.
