  • 27ee59af2   net: execute "miiphy_init" if CONFIG_PHYLIB defined ... Browse Code »

    In "common/Makefile" "miiphyutil.o" gets built if any of the following
    items enabled:
    * CONFIG_PHYLIB
    * CONFIG_MII
    * CONFIG_CMD_MII

    So it's possible to not define CONFIG_MII or CONFIG_CMD_MII and still
    use functions like "miiphy_get_dev_by_name".

    In its turn "miiphy_get_dev_by_name" traverses "mii_devs" list which is
    not initialized because "miiphy_init" never got called.

  • f8be7d659   net: Improve the speed of netconsole ... Browse Code »

    Previously u-boot would initialize the network interface for every
    network operation and then shut it down again. This makes sense for
    most operations where the network in not known to be needed soon after
    the operation is complete. In the case of netconsole, it will use the
    network for every interaction with the shell or every printf. This
    means that the network is being reinitialized very often. On many
    devices, this intialization is very slow.

    This patch checks for consecutive netconsole actions and leaves the
    ethernet hardware initialized between them. It will still behave the
    same old way for all other network operations and any time another
    network operation happens between netconsole operations.

  • 46c07bcf1   api: net: fix length check in eth_receive() ... Browse Code »

    If the requested length is too small to hold the received packet,
    eth_receive() will return -1 and will leave the packet in the receive
    buffers. Instead of returning an error in this case, we return the first
    portion of the received packet and remove it from the receive buffers.

    This fixes FreeBSD's ubldr. Without this patch it will just stop receiving
    packets if the NIC receives more than PKTBUFSRX too large packets.

  • 693766442   net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall back ... Browse Code »

    Ignore the return value of eth_getenv_enetaddr_by_index(), and if it
    fails, fall back to use dev->enetaddr, which could be filled up by
    the ethernet device driver:

    With the current code, introduced with below commit, eth_write_hwaddr()
    will fail immediately if there is no ethaddr in the environment variables.

    However, e.g. for an overo based product that uses the SMSC911x ethernet
    chip (with the MAC address set via EEPROM connected to the SMSC911x chip),
    the MAC address is still OK.

    On mx28 boards that are depending on the OCOTP bits to set the MAC address
    (like the Denx m28 board), the OCOTP bits should be used instead of
    failing on the environment variables.

    Actually, this was the original behavior, and was later changed by
    commit 7616e7850804c7c69e0a22c179dfcba9e8f3f587.

  • fea7dcae5   net: introduce per device index ... Browse Code »

    Instead of counting the device index everytime a functions needs it, store
    it in the eth_device struct. eth_register() keeps track of the indices and
    updates the device's index number. This simplifies some functions in
    net/eth.c.

    Additionally, a network driver can now query its index, eg. to get the
    correct environment ethaddr name.

    The new sanity check introduces a printf warning for some systems:
    eth.c:233: warning: format '%zu' expects type 'size_t', but argument 3 has type 'int'

    Rather than tweak the format string, use the new assert() helper instead.

  • 7616e7850   Add Ethernet hardware MAC address framework to usbnet ... Browse Code »

    Built-in Ethernet adapters support setting the mac address by means of a
    ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr).

    This adds similar support to the USB network side, using the names
    usbethaddr, usbeth1addr, etc. They are kept separate since we don't want
    a USB device taking the MAC address of a built-in device or vice versa.

  • 5f184715e   Create PHY Lib for U-Boot ... Browse Code »

    Extends the mii_dev structure to participate in a full-blown MDIO and
    PHY driver scheme. The mii_dev structure and miiphy calls are modified
    in such a way to allow the original mii command and miiphy
    infrastructure to work as before, but also to support a new set of APIs
    which allow (among other things) sharing of PHY driver code and 10G support

    The mii command will continue to support normal PHY management functions
    (Clause 22 of 802.3), but will not be changed to support 10G
    (Clause 45).

    The basic design is similar to PHY Lib from Linux, but simplified for
    U-Boot's network and driver infrastructure.

    We now have MDIO drivers and PHY drivers

    An MDIO driver provides:
    read
    write
    reset

    A PHY driver provides:
    (optionally): probe
    config - initial setup, starting of auto-negotiation
    startup - waiting for AN, and reading link state
    shutdown - any cleanup needed

    The ethernet drivers interact with the PHY Lib using these functions:
    phy_connect()
    phy_config()
    phy_startup()
    phy_shutdown()

    Each PHY driver can be configured separately, or all at once using
    config_phylib_all_drivers.h (added in the patch which adds the drivers)

    We also provide generic drivers for Clause 22 (10/100/1000), and
    Clause 45 (10G) PHYs.

    We also implement phy_reset(), and call it in phy_connect(). Because
    phy_reset() is essentially the same as miiphy_reset, but:
    a) must support 10G PHYs, and
    b) should use the phylib primitives,

    we implement miiphy_reset, using phy_reset(), but only when
    CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
    way, we save on compile size, even if we don't manage to save code size.

    Pulled ethtool.h and mdio.h from:
    git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6
    782d640afd15af7a1faf01cfe566ca4ac511319d
    With many, many deletions so as to enable compilation under u-boot

  • 8ad25bf8d   Net: clarify board/cpu_eth_init calls ... Browse Code »

    This has always been confusing, and the idea of these functions returning the
    number of interfaces initialized was half-baked and ultimately pointless.
    Instead, act more like regular functions and return < 0 on failure, >= 0 on
    success.

    This change shouldn't break anything.

    Commit 6e37b1a3a25004d3df5867de49fff6b3fc9c4f04 modifies several net calls
    to take a (const char *) parameter instead of (char *), but in some cases
    the modified functions call other functions taking (char *). The end result
    is warnings about discarding the const qualifier.

    This patch fixes these other function signatures.
