3b2663ca84 mips: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

17d97bad1a MIPS: bcm63xx: cpu: Replace BUG() with panic()
BUG() can be a noop if CONFIG_BUG is not selected,
leading to the following build problem on a randconfig:

arch/mips/bcm63xx/cpu.c: In function 'detect_cpu_clock':
arch/mips/bcm63xx/cpu.c:254:1: error: control reaches end of
non-void function [-Werror=return-type]

We fix this problem by replacing BUG() with panic() since it's
best to handle the case of an unknown board instead of silently
returning a random clock frequency.

6465460c92 MIPS: BMIPS: change compile time checks to runtime checks
Allow building for all bmips cpus at the same time by changing ifdefs
to checks for the cpu type, or adding appropriate checks to the

Since BMIPS43XX and BMIPS5000 require different IPI implementations,
split the SMP ops into one for each, so the runtime overhead is only
at registration time for them.

7b9334215f MIPS: BCM63XX: add support for BCM3368 Cable Modem
The Broadcom BCM3368 Cable Modem SoC is extremely similar to the
existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort
in the existing code base is required to get it supported. This patch adds
support for the following on-chip peripherals:

- two UARTS
- GPIO
- Ethernet
- SPI
- PCI
- NOR Flash

The most noticeable difference with 3368 is that it has its peripheral
register at 0xfff8_0000 we check that separately in ioremap.h. Since
3368 is identical to 6358 for its clock and reset bits, we use them
verbatim.

3dc6475c0c bcm63xx_enet: add support Broadcom BCM6345 Ethernet
This patch adds support for the Broadcom BCM6345 SoC Ethernet. BCM6345
has a slightly different and older DMA engine which requires the
following modifications:

- the width of the DMA channels on BCM6345 is 64 bytes vs 16 bytes,
  which means that the helpers enet_dma{c,s} need to account for this
  channel width and we can no longer use macros

- BCM6345 DMA engine does not have any internal SRAM for transfering
  buffers

- BCM6345 buffer allocation and flow control is not per-channel but
  global (done in RSET_ENETDMA)

- the DMA engine bits are right-shifted by 3 compared to other DMA
  generations

- the DMA enable/interrupt masks are a little different (we need to
  enabled more bits for 6345)

- some register have the same meaning but are offsetted in the ENET_DMAC
  space so a lookup table is required to return the proper offset

The MAC itself is identical and requires no modifications to work.

6f00a02296 bcm63xx_enet: add support for Broadcom BCM63xx integrated gigabit switch
Newer Broadcom BCM63xx SoCs: 6328, 6362 and 6368 have an integrated switch
which needs to be driven slightly differently from the traditional
external switches. This patch introduces changes in arch/mips/bcm63xx in order
to:

- register a bcm63xx_enetsw driver instead of bcm63xx_enet driver
- update DMA channels configuration & state RAM base addresses
- add a new platform data configuration knob to define the number of
  ports per switch/device and force link on some ports
- define the required switch registers

On the driver side, the following changes are required:

- the switch ports need to be polled to ensure the link is up and
  running and RX/TX can properly work
- basic switch configuration needs to be performed for the switch to
  forward packets to the CPU
- update the MIB counters since the integrated

0ae99b5fed bcm63xx_enet: split DMA channel register accesses
The current bcm63xx_enet driver always uses bcmenet_shared_base whenever
it needs to access DMA channel configuration space or access the DMA
channel state RAM. Split these register in 3 parts to be more accurate:

- global DMA configuration
- per DMA channel configuration space
- per DMA channel state RAM space

This is preliminary to support new chips where the global DMA
configuration remains the same, but there is a varying number of DMA
channels located at a different memory offset.

Pull MIPS updates from Ralf Baechle:

 - More work on DT support for various platforms

 - Various fixes that were to late to make it straight into 3.9

 - Improved platform support, in particular the Netlogic XLR and
   BCM63xx, and the SEAD3 and Malta eval boards.

 - Support for several Ralink SOC families.

 - Complete support for the microMIPS ASE which basically reencodes the
   existing MIPS32/MIPS64 ISA to use non-constant size instructions.

 - Some fallout from LTO work which remove old cruft and will generally
   make the MIPS kernel easier to maintain and resistant to compiler
   optimization, even in absence of LTO.

 - KVM support.  While MIPS has announced hardware virtualization
   extensions this KVM extension uses trap and emulate mode for
   virtualization of MIPS32.  More KVM work to add support for VZ
   hardware virtualizaiton extensions and MIPS64 will probably already
   be merged for 3.11.

Most of this has been sitting in -next for a long time.  All defconfigs
have been build or run time tested except three for which fixes are being
sent by other maintainers.

13be798c57 MIPS: BCM63XX: rework chip detection
Instead of trying to use a correlation of cpu prid and chip id and
hoping they will always be unique, use the cpu prid to determine the
chip id register location and just read out the chip id.

8a398d757d MIPS: BCM63XX: remove duplicate spi register definitions
BCM6338 and BCM6348, and BCM6358 and everything after that share the
same register layout. To not have to redefine them for each new chip
and keep the code size small, only use the definitions for the first
chip with the certain layout.

61f3d0a988 spi: Updates for v3.10
A fairly quiet release for SPI, mainly driver work.  A few highlights:
 
 - Supports bits per word compatibility checking in the core.
 - Allow use of the IP used in Freescale SPI controllers outside
   Freescale SoCs.
 - DMA support for the Atmel SPI driver.
 - New drivers for the BCM2835 and Tegra114.

1762c5ab7c Revert "MIPS: BCM63XX: Call board_register_device from device_initcall()"
This commit causes a race between PCI scan and SSB fallback SPROM handler
registration, causing the wifi to not work on slower systems. The only
subsystem touched from board_register_devices is platform device
registration, which is safe as an arch init call.

This reverts commit d64ed7ada2 [MIPS:
BCM63XX: Call board_register_device from device_initcall()].

f7be4e754b MIPS: early_printk: drop __init annotations
We cannot use __init for earlyprintk code or data, since the kernel
parameter "keep_bootcon" allows leaving the boot console enabled.

Currently MIPS will crash/hang/die if you use keep_bootcon. The patch
fixes it at least on Lemote FuLoong mini-PC. Changes for other boards
were done based on what I could find with grep...

Implement the correct checksum calculation by calculating the crc32 with
the checksum field set to 0.

Pull MIPS update from Ralf Baechle:
 "This is the MIPS update for 3.7.

  A fair chunk of them are platform updates to the Cavium Octeon SOC
  (which involves machine generated header files of considerable size),
  Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx
  platforms.

  Support for the commercial MIPS simulator MIPSsim has been removed as
  MIPS Technologies is shifting away from this product and Qemu is
  offering various more powerful platforms.  The generic MIPS code can
  now also probe for no-execute / write-only TLB features implemented
  without the full SmartMIPS extension as permitted by the latest MIPS
  processor architecture.  Lots of small changes to generic code."
