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/.

help
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.
MIPS: BCM47xx: Move SPROM driver to drivers/firmware/ Broadcom ARM home routers store SPROM content in NVRAM just like MIPS ones. To share SPROM code we need to move it out of arch/mips/ to some common place. We already have bcm47xx_nvram in firmware path and SPROM should fit there as well. This driver is responsible for parsing SoC configuration data into a struct shared between ssb and bcma buses. This was tested with BCM4706 & BCM5357C0 (BCM47XX) and BCM4708A0 (ARCH_BCM_5301X).

help
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.
