2015-11-11MIPS: BCM47xx: Fetch board info directly in callback functionRafał Miłecki
This drops another symbol dependency between setup.c and sprom.c which will allow us to make SPROM code a separated module (and share it with ARM). Patch tested on Linksys WRT300N V1.

2015-09-03MIPS: Remove all the uses of custom gpio.hAlban Bedel
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

2015-04-01MIPS: BCM47xx: Move NVRAM header to the include/linux/.Rafał Miłecki
There are two reasons for having this header in the common place: 1) Simplifying drivers that read NVRAM entries. We will be able to safely call bcm47xx_nvram_* functions without #ifdef-s. 2) Getting NVRAM driver out of MIPS arch code. This is needed to support BCM5301X arch which also requires this NVRAM driver. Patch for that will follow once we get is reviewed.

This was crated by checking the features of a BCM4712, BCM4704, BCM5354, BCM4716 and BCM4706 SoC and then tested on these SoCs.

In addition some values like boardtype are stored without a prefix for the main SoC chip also when they have an additional PCIe wifi chip with an own boardtype var on some devices.
