    Commit 6af1d41 "smc911x MII made available" was missing a few "const"
    qualifiers. Fix the resulting in build warnings:

    smc911x.c: In function 'smc911x_initialize':

  • 8ef583a03   miiphy: convert to linux/mii.h ... Browse Code »

    The include/miiphy.h header duplicates a lot of things from linux/mii.h.
    So punt all the things that overlap to keep the API simple and to make
    merging between U-Boot and Linux simpler.

  • bd75db3fe   smc911x driver frame alignment patch ... Browse Code »

    SMSC911x chips have alignment function to allow frame payload data
    (which comes after 14-bytes ethernet header) to be aligned at some
    boundary when reading it from fifo (usually - 4 bytes boundary).
    This is done by inserting fake zeros bytes BEFORE actual frame data when
    reading from SMSC's fifo.
    This function controlled by RX_CFG register. There are bits that
    represents amount of fake bytes to be inserted.

    Linux uses alignment of 4 bytes. Ethernet frame header is 14 bytes long,
    so we need to add 2 fake bytes to get payload data aligned at 4-bytes
    boundary.
    Linux driver does this by adding IP_ALIGNMENT constant (defined at
    skb.h) when calculating fifo data length. All network subsystem of Linux
    uses this constant too when calculating different offsets.

    But u-boot does not use any packet data alignment, so we don't need to
    add anything when calculating fifo data length.
    Moreover, driver zeros the RX_CFG register just one line up, so chip
    does not insert any fake data at the beginig. So calculated data length
    is always bigger by 1 word.

    It seems that at almost every packet read we get an underflow condition
    at fifo and possible corruption of data. Especially at continuous
    transfers, such as tftp.

    Just after removing this magic addition, I've got tftp transfer speed as
    it aught to be at 100Mbps. It was really slow before.

    It seems that fifo underflow occurs only when using byte packing on
    32-bit blackfin bus (may be because of very small delay between reads).

  • 76771e595   NET: Fix MAC addr handling for smc911x ... Browse Code »

    This patch turns off MAC address mismatch warning when
    optional eeprom programmed with MAC address is not available.
    In that case, smc911x's MAC address register has its default
    value ff:ff:ff:ff:ff:ff and it's not a valid address. This
    makes eth_initialize() show the warning which has no
    meaningful information while environment variable ethaddr
    overrides the address read from the register. If there's no
    eeprom and the value of MAC address register is not valid
    after initialization, dev->enetaddr had better not be updated
    and maintain its initial value 00:00:00:00:00:00, which I
    think is what eth_initialize() expects. This is not a bug fix.
    Even without this patch, the driver works fine. It's just for
    enhancing the way of displaying messages.

  • 2a6cc97b9   SMC911X: Add chip auto detection ... Browse Code »

    Refactor the smc911x driver to allow for detecting when the chip is missing.
    I.e. the detect_chip() function is called earlier and will abort gracefully
    when the Chip ID read returns all 1's.

  • c3147c176   Revert "SMC911x driver fixed for NFS boot" ... Browse Code »

    This reverts commit ca9c8a1e10fac01e6a1129f82a7ce18bd818fa43,
    which causes compile warnings ("large integer implicitly truncated
    to unsigned type") on all systems that use this driver. The warning
    results from passing long constants (TX_CFG, RX_CFG) into
    smc911x_set_mac_csr() which is declared to accept "unsigned
    character" arguments only.

    Being close to a release, with nobody available to actually test the
    code or the suggested fixes, it seems better to revert the patch.

  • ca9c8a1e1   SMC911x driver fixed for NFS boot ... Browse Code »

    eth_halt() function in the smc911x drivers used to call the
    smc911x_reset() function. eth_halt() used to be called after
    tftp transfers. This used to put the ethernet chip in reset
    while the linux boots up resulting in the ethernet driver
    not coming up. NFS boot used to fail as a result.

    This patch calls smc911x_shutdown() instead of smc911x_reset().
    Some comments received has also been fixed.

  • 03f3d8d3b   lan91c96/smc91111/smc911x: get mac address from environment ... Browse Code »

    The environment is the canonical storage location of the mac address, so
    we're killing off the global data location and moving everything to
    querying the env directly.

    Also, do not bother checking the EEPROM if the env is setup. This
    simplifies the code greatly.

    The smc911x driver has a lot of useful defines/functions which can be used
    by pieces of code (such as example eeprom programmers). Rather than
    forcing each place to duplicate these defines/functions, split them out
    of the smdc911x driver into a local header.

    The RSK7203 board has the SMSC9118 wired up 'incorrectly'.
    Byte-swapping is necessary, and so poor performance is inevitable.
    This problem cannot evade by the swap function of CHIP, this can
    evade by software Byte-swapping.
    And this has problem by FIFO access only. pkt_data_pull/pkt_data_push
    functions necessary to solve this problem.

    This commit gets rid of a huge amount of silly white-space issues.
    Especially, all sequences of SPACEs followed by TAB characters get
    removed (unless they appear in print statements).

    Also remove all embedded "vim:" and "vi:" statements which hide

    When applying the AT91CAP9 patches upstream, something transformed
    the '@' character into the ' ' sequence.

    The patch below restores the original form in all the places where
    it has been modified (the AT91CAP9 files, the AT91SAM9260 files which
    were copied from AT91CAP9, and a couple of other files where the
    ' ' sequence was present).
