  • The attached patch corrects an error in the examples/Makefile which
    causes the applications in the examples directory to hang on OMAP3
    based boards. The current Makefile sets -Ttext during linking to
    0x0c100000 which is outside of addressable SDRAM memory. The script
    corrects the existing ifeq...else...endif logic to look at the VENDOR
    tag rather than the CPU tag.

    The patch affects the following configs: omap3_beagle_config,
    omap3_overo_config, omap3_evm_config, omap3_pandora_config,
    omap3_zoom1_config and omap3_zoom2_config.

  • replace variable types in ctrl_structs for omap3 by those with
    fixed size (u8, u16, u32).
    Additional ifndef-protection is needed by examples which do not
    compile when including asm/types.h

  • In the previous enetaddr refactoring, the assumption with commit 56b555a644
    was that the eth layer would handle the env -> device enetaddr syncing.
    This was not the case as eth_initialize() is called only once and the sync
    occurs there. So make sure the eth_init() function does the env -> device
    sync with every network init.

  • Minor ./net cleanups - no functional changes
    - change #ifdef DEBUG printf(); #endif to just debug()
    - changed __FUNCTION__ to __func__
    - got rid of extra whitespace between function and opening brace
    - removed unnecessary braces on if statements

    gcc dead code elimination should make this functionally/size equivalent
    when DEBUG is not defined. (confirmed on Blackfin, with gcc 4.3.3).

  • For some reason the AT91rm9200 lowlevel init writes to a bunch of
    reserved or read-only addresses. All the boards seem to define the
    value-to-be-written values as zero ... but they shouldn't actually
    be writing *anything* there.

    No documented erratum justifies these accesses. It looks like maybe
    some pre-release BDI-2000 setup code has been carried along by cargo
    cult programming since at least late 2004 (per GIT history).

    Here's a patch disabling what seems to be bogosity. Tested on a
    csb337; there were no behavioral changes.

  • The Zoom2 power reset button is on the top right side of the
    main board. Press and hold for about to 8 seconds to completely
    reset the board.

    Some of the beta boards have a hardware problem that prevents
    using this feature. If is difficult to further characterize the
    boards that fail. So disable resetting for all beta boards.

    The Zoom1 reset button is the red circle on the top right,
    front of the board. Press and hold the button for 8 seconds to
    completely reset the board.

    After analyzing beagle, it was determined that other boards
    that use the twl4030 for power managment can also make use
    this function.

    The resetting is done by the power management part of the twl4030.
    Since there is no existing drivers/power, add one.

    The compilation of power/twl4030.h is controlled by the config
    variable CONFIG_TWL4030_POWER

    power management, usb and, keyboard.

  • This problem is seen on Zoom1 and Zoom2 in the startup and
    when i2c probe is used

    After :

    In: serial
    Out: serial
    Err: serial
    Die ID #327c00020000000004013ddd05026013
    Hit any key to stop autoboot: 0
    OMAP3 Zoom1# i2c probe
    Valid chip addresses: 48 49 4A 4B

    The addresses are for the twl4030.

    The prescalar that converts the function clock to the sampling
    clock is hardcoded to 0. The reference manual recommends 7
    if the function clock is 96MHz.

    Instead of just changing the hardcoded values, the prescalar
    is calculated from the value I2C_IP_CLK.

    The i2c #defines are in kHz. The speed passed into the
    i2c init routine is in Hz. To be consistent, change the
    defines to be in Hz.

    The timing calculations are based on what is done in the
    linux 2.6.30 kernel in drivers/i2c/buses/i2c_omap.c as
    apposed to what is done in TRM.

    The major variables in the timing caculations are
    specified as #defines that can be overriden as required.

    The variables and their defaults are

    I2C_IP_CLK SYSTEM_CLOCK_96
    I2C_INTERNAL_SAMPLING_CLK 19200000
    I2C_FASTSPEED_SCLL_TRIM 6
    I2C_FASTSPEED_SCLH_TRIM 6
    I2C_HIGHSPEED_PHASE_ONE_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM
    I2C_HIGHSPEED_PHASE_ONE_SCLH_TRIM I2C_FASTSPEED_SCLH_TRIM
    I2C_HIGHSPEED_PHASE_TWO_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM
    I2C_HIGHSPEED_PHASE_TWO_SCLH I2C_FASTSPEED_SCLH_TRIM

    This was runtime verified on Zoom1, Zoom2, Beagle and Overo.
    The 400kHz and 3.4M cases were verifed on test Zoom1,
    Zoom2, Beagle and Overo configurations.

    Testing for omap2 will be done in a second step as Nishanth
    and Jean-Christophe commented.

  • This patch fixes the problem, that the current fdt board fixup code only
    set's one range, the one for NOR. By this it's overwriting the already
    correctly configured values done in __ft_board_setup(). Just remove this
    now unneeded NOR fixup and all the ranges are correctly defined.

  • This patch adds some I2C bootstrap setting for NAND booting to the Kilauea
    chip_config command ("533-nand" and "600-nand").

    Additionally some incorrectly indented lines are fixed.

  • DDR2 Auto-calibration needs to be disabled on the NAND booting PPC4xx
    targets. Otherwise the configured fixed init values for some DDR2
    controller registers (e.g. RQDC) are not initialized at all resulting
    in a non working SDRAM.

  • Testing on AMCC Arches with the latest U-Boot version yielded that DDR2
    initialization is currently broken. U-Boot hangs upon relocation to SDRAM
    or crashes with random traps. This patch fixes this problem. Arches now
    uses a different WRDTR and CLKTR default setting than Canyonlands/Glacier.
