  • 1b387ef55   SPDX: fix IBM-pibs license identifier ... Browse Code »

    The SPDX License List version 1.19 now contains an official entry for
    the IBM-pibs license. However, instead of our suggestion "ibm-pibs",
    the SPDX License List uses "IBM-pibs", with the following rationale:
    "The reason being that all other SPDX License List short identifiers
    tend towards using capital letters unless spelling a word. I'd prefer
    to be consistent to this end".

    Change the license IDs to use the official name.

  • 46263f2de   SPDX-License-Identifier: convert PIBS licensed files ... Browse Code »

    This commit adapts the files that were derived from PIBS (PowerPC
    Initialization and Boot Software) codeto using SPDX License
    Identifiers.

    So far, SPDX has not assigned an official License ID for the PIBS
    license yet, so this should be considered preliminary.

    Note that the following files contained incorrect license information:

    arch/powerpc/cpu/ppc4xx/4xx_uart.c
    arch/powerpc/cpu/ppc4xx/start.S
    arch/powerpc/include/asm/ppc440.h

    These files included, in addition to the GPL-2.0 / ibm-pibs dual
    license as inherited from PIBS, a GPL-2.0+ license header which was
    obviously incorrect. This has been removed.

  • f6add132f   net/miiphy/serial: drop duplicate "NAMESIZE" define ... Browse Code »

    A few subsystems are using the same define "NAMESIZE". This has been
    working so far because they define it to the same number. However, I
    want to change the size of eth_device's NAMESIZE, so rather than tweak
    the define names, simply drop references to it. Almost no one does,
    and the handful that do can easily be changed to a sizeof().

    This reverts commit 5c45a22b9203351a32aec4600514341b91175542.

    It causes a lot of "incompatible pointer type" warnings for a large
    number of Ethernet drivers, which are not really worth fixing
    especially as this patch was only supposed to help the old,
    deprecated miiphy API. Instead of adding more efforts to a lost case
    we rather revert it.

    This patch is added for PHY whose register offset value exceeds 0xFF and
    cannot be used with "unsigned char" datatype in miiphy_read, miiphy_write
    and miiphy_register functions. Datatype of register offset is changed to
    unsigned short instead of unsigned char so that offset value greater then
    0xFF can be used.

  • 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

  • 4ba31ab33   Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrar… ... Browse Code »

    …y number of mii buses.

    This feature is useful when your board uses different mii buses for different
    phys and all (or a part) of these buses are implemented via bit-banging mode.

    The driver requires that the following macros should be defined into the board
    configuration file:

    CONFIG_BITBANGMII - Enable the miiphybb driver
    CONFIG_BITBANGMII_MULTI - Enable the multi bus support

    If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
    to define at least the following macros:

    MII_INIT - Generic code to enable the MII bus (optional)
    MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
    MDIO_ACTIVE - Activate the MDIO pin as out pin
    MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
    MDIO_READ - Read the MDIO pin
    MDIO(v) - Write v on the MDIO pin
    MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
    MDC(v) - Write v on the MDC pin

    The previous macros make the driver compatible with the previous version
    (that didn't support the multi-bus).

    When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
    the bb_miiphy_buses[] array with a record for each required bus and declare
    the bb_miiphy_buses_num variable with the number of mii buses.
    The record (struct bb_miiphy_bus) has the following fields/callbacks (see
    miiphy.h for details):

    char name[] - The symbolic name that must be equal to the MII bus
    registered name
    int (*init)() - Initialization function called at startup time (just
    before the Ethernet initialization)
    int (*mdio_active)() - Activate the MDIO pin as output
    int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
    int (*set_mdio)() - Write the MDIO pin
    int (*get_mdio)() - Read the MDIO pin
    int (*set_mdc)() - Write the MDC pin
    int (*delay)() - Delay function
    void *priv - Private data used by board specific code

    The board code will look like:

    struct bb_miiphy_bus bb_miiphy_buses[] = {
    { .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
    { .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
    ...
    int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
    sizeof(bb_miiphy_buses[0]);

  • 317734966   Dual-license IBM code contributions ... Browse Code »

    It was brought to our attention that U-Boot contains code derived from the
    IBM OpenBIOS source code originally provided with some of the older PowerPC
    4xx development boards. As a result, the original license of this code has
    been carried in the various files for a number of years in the U-Boot project.

    IBM is dual-licensing the IBM code contributions already present in U-Boot
    under either the terms of the GNU General Public License version 2, or the
    original code license already present.
