    This fixes a Data bus error on some SoCs. The first fix for this
    problem did not solve it on all devices.

    ssb: fix init regression of hostmode PCI core

    In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is
    accessed, but the sprom only exists when the ssb bus is connected over
    a PCI bus to the rest of the system and not when the SSB Bus is the
    main system bus. SoCs sometimes have a PCI host controller and there
    this code will not be executed, but there are some old SoCs with an PCI
    controller in client mode around and ssb_pcicore_fix_sprom_core_index()
    should not be called on these devices too. The PCI controller on these
    devices are unused, but without this fix it results in an Data bus
    error when it gets initialized.

  • cd1559870   ssb: add __devinit to some functions ... Browse Code »

    Two functions in ssb are using register_pci_controller() which is
    __devinit. The functions ssb_pcicore_init_hostmode() and
    ssb_gige_probe() should also be __devinit.

    This fixes the following warning:
    WARNING: vmlinux.o(.text+0x2727b8): Section mismatch in reference from the function ssb_pcicore_init_hostmode() to the function .devinit.text:register_pci_controller()
    The function ssb_pcicore_init_hostmode() references
    the function __devinit register_pci_controller().
    This is often because ssb_pcicore_init_hostmode lacks a __devinit
    annotation or the annotation of register_pci_controller is wrong.

    WARNING: vmlinux.o(.text+0x273398): Section mismatch in reference from the function ssb_gige_probe() to the function .devinit.text:register_pci_controller()
    The function ssb_gige_probe() references
    the function __devinit register_pci_controller().
    This is often because ssb_gige_probe lacks a __devinit
    annotation or the annotation of register_pci_controller is wrong.

  • 847253b94   MIPS: Fix SSB PCIcore IO resource management ... Browse Code »

    The SSB PCIcore code reused the IO resource fixup code from the original
    2.4.x Broadcom patch for BCM47xx based devices, which was a quick hack
    for doing PCI IO resource configuration back then (the boot loader
    doesn't configure PCI devices on this platform).

    However, this code is no longer necessary since the kernel now can do
    PCI resource management fine all by itself, so remove the old code.

    When removing the code, it becomes obvious that the mem_offset setting
    in the PCIcore driver was wrong, however this was masked by the fixup
    code before, except in a few cases involving yenta_socket. For BCM47xx,
    the correct offset is 0, and since this is the only device using PCIcore
    in host mode, the offset can simply be removed unconditionally.

  • aab547ce0   ssb: Add Gigabit Ethernet driver ... Browse Code »

    This adds the Gigabit Ethernet driver for the SSB
    Gigabit Ethernet core. This driver actually is a frontend to
    the Tigon3 driver. So the real work is done by tg3.
    This device is used in the Linksys WRT350N.

  • 61e115a56   [SSB]: add Sonics Silicon Backplane bus support ... Browse Code »

    SSB is an SoC bus used in a number of embedded devices. The most
    well-known of these devices is probably the Linksys WRT54G, but there
    are others as well. The bus is also used internally on the BCM43xx
    and BCM44xx devices from Broadcom.

    This patch also includes support for SSB ID tables in modules, so
    that SSB drivers can be loaded automatically.
