0dae62edfd MIPS: BCM47XX: Add Belkin F7Dxxxx board detection
Add a few Belkin F7Dxxxx entries, with F7D4401 sourced from online
documentation and the "F7D7302" being observed. F7D3301, F7D3302, and
F7D4302 are reasonable guesses which are unlikely to cause
mis-detection.

d508eb79ab MIPS: BCM47XX: Add detection and GPIO config for Siemens SE505v2
This adds board detection for the Siemens SE505v2 and the led gpio
configuration. This board does not have any buttons.
This is based on OpenWrt broadcom-diag and Manuel Munz's nvram dump.

848eeb66c7 MIPS: BCM47XX: Detect some more Linksys devices
The Linksys WRT54G/GS/GL family uses the same boardtype numbers, and
the same gpio configuration. The boardtype numbers are changing with
the hardware versions, but these hardware numbers are different or each
model.
Detect them all as one device, this also worked in OpenWrt.

cdfc83075f Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
 "The most notable new addition inside this pull request is the support
  for MIPS's latest and greatest core called "inter/proAptiv".  The
  patch series describes this core as follows.

    "The interAptiv is a power-efficient multi-core microprocessor
     for use in system-on-chip (SoC) applications. The interAptiv combines
     a multi-threading pipeline with a coherence manager to deliver improved
     computational throughput and power efficiency. The interAptiv can
     contain one to four MIPS32R3 interAptiv cores, system level
     coherence manager with L2 cache, optional coherent I/O port,
     and optional floating point unit."

  The platform specific patches touch all 3 Broadcom families.  It adds
  support for the new Broadcom/Netlogix XLP9xx Soc, building a common
  BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count
  and full gpio button/led descriptions for BCM47xx.

  The rest of the series are cleanups and bug fixes that are MIPS
  generic and consist largely of changes that Imgtec/MIPS had published
  in their linux-mti-3.10.git stable tree.  Random other cleanups and
  patches preparing code to be merged in 3.15"

6404b7cb83 MIPS: BCM47XX: use fallback sprom var for board_{rev,type}
An SoC normally do not define path variables for board_rev and
board_type and the Broadcom SDK also uses the nvram values without a
prefix in such cases. Do the same to fill these sprom attributes from
nvram and do not leave them empty, because brcmsmac do not like this.

924ffb7dba MIPS: BCM47XX: trim the nvram values for parsing
Some nvram values on some devices have a newline character at the end
of the value, that caused read errors. Trim the string before reading
the number.

111bd981e2 MIPS: BCM47XX: add bcm47xx prefix in front of nvram function names
The nvram functions are exported and used by some normal drivers. To
prevent name clashes with ofter parts of the kernel code add a bcm47xx_
prefix in front of the function names and the header file name.

f36738ddfe MIPS: BCM47XX: handle different nvram sizes
The old code just worked for nvram with a size of 0x8000 bytes. This
patch adds support for reading nvram from partitions of 0xF000 and
0x10000 bytes.

There is just 32KB space for the nvram, but most devices do not use the
full size and this code reads the first 32KB in that case and prints a
warning.

This makes it possible to handle the case of not being able to read the
nvram ram. This could happen when the code searching for the specific
flash chip have not run jet.
