  • 017c4c3bd   bcma: use fallback sprom if sprom on card was not valid ... Browse Code »

    Sometimes the PCIe card indicates that it has a sprom somewhere and we
    are able to read the memory region, but it is empty and not valid. In
    these cases we should try to use the fallback sprom as a last chance.

    This is the case for the PCIe cards in my ASUS RT-N66U (BCM4706 + 2
    times BCM4331) and I have heard of someone having the same problem with
    an other PCIe card connected to an other Broadcom SoC.

  • 3d9d8af33   bcma: use custom printing functions ... Browse Code »

    Having bus number printed makes it much easier to anaylze logs on
    systems with more buses. For example Netgear WNDR4500 has 3 AMBA buses
    in total, which makes standard log really messy.

    The chip IDs are used all over bcma and no constants where defined.
    This patch adds the constants and makes bcma use them.

  • 69aaedd3c   bcma: add ext PA workaround for BCM4331 and BCM43431 ... Browse Code »

    MacBook Pro models with BCM4331 wireless have been found to have the ext
    PA lines disabled after resuming from S3 without external power attach.
    This causes them to be unable to transmit. Add a workaround to ensure
    that the ext PA lines are enabled on BCM4331. Also extend all handling
    of ext PA line muxing to BCM43431 as is done in the Broadcom SDK.

    The attribute country_code and alpha2 are two different attributes in

    sprom version 1.

  • 32998cc96   bcma: use fallback sprom if no on chip sprom is available ... Browse Code »

    bcma should check for a fallback sprom every time it can not find a
    sprom on the card itself or a normal external sprom mapped into the
    memory of the chip. When otp sprom support was introduced it tried to
    read out the sprom from the wireless chip also if no otp sprom was
    available. This caused a Data bus error in bcma_sprom_get() when
    reading out the sprom for the SoC.

    This fixes a regression introduced in commit:

    Wireless Broadcom chips can have either their SPROM data stored
    on either external SPROM or on-chip OTP memory. Both are accessed
    through the same register space. This patch adds support for the
    on-chip OTP memory.

    Tested with:
    BCM43224 OTP and SPROM
    BCM4331 SPROM
    BCM4313 OTP

    This patch is in response to linux-wireless thread [1].

    When not SPROM is available a fallback mechanism is used. However,
    when that fails the code currently continues. This patch assures
    that the bcma_sprom_get() function aborts when that happens.

  • a027237a5   bcma: add support for sprom not found on the device ... Browse Code »

    On SoCs the sprom is stored in the nvram in a special partition on the
    flash chip. The nvram contains the sprom for the main bus, but
    sometimes also for a pci devices using bcma. This patch makes it
    possible for the arch code to register a function to fetch the needed
    sprom from the nvram and provide it to the bcma code.

  • 534e7a456   bcma: add check if sprom is available before accessing it. ... Browse Code »

    The SoCs like the bcm4716 do not have a sprom on the bcma bus like a
    pcie device. It stores the values in some partition on flash memory.
    For ssb this informations are read out in the bcm47xx arch code,
    something like that should also be implemented for bcma. Without this
    patch bcma panics on SoCs.

  • 27f18dc2d   bcma: read SPROM and extract MAC from it ... Browse Code »

    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.
