  • This follows the way of handling other flashes and cleans code a bit. As
    next task we will want to move flash code to ChipCommon driver as:
    1) Flash controllers are accesible using ChipCommon registers
    2) This code isn't MIPS specific
    This change prepares bcma for that.

  • Driver for PCIe core requires PCI to be enabled, however we shouldn't
    require it for the whole bus. Someone may be not interested in extra
    PCI devices and what's more there are SoCs without any PCI at all (like
    BCM5356C0, BCM5357*, BCM47186B0). For more details see Kconfig "help".
    Please note this patch doesn't allow disabling PCI drivers yet, as it
    requires more work on calls to bcma_core_pci_* functions.

  • Register a GPIO driver to access the GPIOs provided by the chip.
    The GPIOs of the SoC should always start at 0 and the other GPIOs could
    start at a random position. There is just one SoC in a system and when
    they start at 0 the number is predictable.

  • This adds a mips driver to bcma. This is only found on embedded
    devices. For now the driver just initializes the irqs used on this
    system.

  • This patch adds support for using bcma on a Broadcom SoC as the system
    bus. An SoC like the bcm4716 could register this bus and use it to
    searches for the bcma cores and register the devices on this bus.

    BCMA_HOSTTYPE_NONE was intended for SoCs at first but BCMA_HOSTTYPE_SOC
    is a better name.

  • In case of BCMA cards SPROM is located in the ChipCommon core, it is
    not mapped as separated host window. So far we have met only SPROMs rev
    8.
    SPROM layout seems to be the same as for SSB buses, so we decided to
    share SPROM struct and some defines.
    For now we extract MAC address only, this can be improved of course.

  • Broadcom has released cards based on a new AMBA-based bus type. From a
    programming point of view, this new bus type differs from AMBA and does
    not use AMBA common registers. It also differs enough from SSB. We
    decided that a new bus driver is needed to keep the code clean.

    In its current form, the driver detects devices present on the bus and
    registers them in the system. It allows registering BCMA drivers for
    specified bus devices and provides them basic operations. The bus driver
    itself includes two important bus managing drivers: ChipCommon core
    driver and PCI(c) core driver. They are early used to allow correct
    initialization.

    Currently code is limited to supporting buses on PCI(e) devices, however
    the driver is designed to be used also on other hosts. The host
    abstraction layer is implemented and already used for PCI(e).

    Support for PCI(e) hosts is working and seems to be stable (access to
    80211 core was tested successfully on a few devices). We can still
    optimize it by using some fixed windows, but this can be done later
    without affecting any external code. Windows are just ranges in MMIO
    used for accessing cores on the bus.
