  • 3b2663ca8   mips: delete non-required instances of include <linux/init.h> ... Browse Code »

    None of these files are actually using any __init type directives
    and hence don't need to include . Most are just a
    left over from __devinit and __cpuinit removal, or simply due to
    code getting copied from one driver to the next.

  • 17d97bad1   MIPS: bcm63xx: cpu: Replace BUG() with panic() ... Browse Code »

    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.

  • 7aa2d0529   MIPS: BCM63xx: CLK: Add dummy clk_{set,round}_rate() functions ... Browse Code »

    Several drivers use the clk_{set,round}_rate() functions
    that need to be defined in the platform's clock code.
    The Broadcom BCM63xx platform hardcodes the clock rate so
    we create new clk_{set,round}_rate() functions
    which just return 0 like those in include/linux/clk.h
    for the common clock framework do.

    Also fixes the following build problem on a randconfig:
    drivers/built-in.o: In function `nop_usb_xceiv_probe':
    phy-nop.c:(.text+0x3ec26c): undefined reference to `clk_set_rate'

    This involves two changes to the BSP code:

    2) The CPU1 boot vector on some of the BCM63xx platforms conflicts with

  • 7b9334215   MIPS: BCM63XX: add support for BCM3368 Cable Modem ... Browse Code »

    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.

    Remove the bogus selects on USB-related symbols for 6345 and 6338, not
    only we do not yet support USB on BCM63XX, but they also cause the
    following warnings:

    warning: (BCM63XX_CPU_6338 && BCM63XX_CPU_6345) selects
    USB_OHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies

  • 3dc6475c0   bcm63xx_enet: add support Broadcom BCM6345 Ethernet ... Browse Code »

    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.

    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

  • 0ae99b5fe   bcm63xx_enet: split DMA channel register accesses ... Browse Code »

    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.
