  • 2a766db93   ARM: davinci: SPL: fix BSS initialization ... Browse Code »

    U-Boot README recommends initializing SDRAM in board_init_f(). DA850
    was doing it as part of board_init_r() (through call to spl_board_init()
    which calls arch_cpu_init() which calls da850_ddr_setup())

    This worked fine till commit 15b8c7505819 ("davinci:
    da850evm/omapl138-lcdk: Move BSS to SDRAM because SRAM is full") moved
    BSS to SDRAM.

    Functions like mmc_initialize() called in board_init_r() assume BSS is
    available. Since SDRAM was not initialized when arch/arm/lib/crt0.S tried
    to initialize BSS to 0, BSS is not initialized correctly.

    Fix this by simply calling arch_cpu_init() from board_init_f(). Also move
    preloader_console_init() there to help debug issues with board_init_r().

    With this spl_board_init() is no longer needed, we remove it.

    Tested using MMC/SD boot on OMAP-L138 LCDK board.

    Now that CMD_UBI does not select CMD_MTDPARTS we need to make platforms
    that had been enabling it turn it on by hand. This exposed that we had
    not yet migrated CMD_MTDPARTS fully, so do so now.

    - CONFIG_NR_DRAM_BANKS_MAX was defined and then used for
    CONFIG_NR_DRAM_BANKS after a check, just migrate it over now.
    - CONFIG_NR_DRAM_BANKS was very oddly defined on p2771-0000-* (to 1024 +

    This converts the following to Kconfig:
    CONFIG_SPI

    This partly involves updating code that assumes that CONFIG_SPI implies
    things that are specific to the MPC8xx SPI driver. For now, just update
    the CONFIG tests. This also involves reworking the default for
    CONFIG_SYS_DEF_EEPROM_ADDR so that we don't set it when we cannot make a
    reasonable default, as it does not cause any compile failures.

    commit 1601dd97edc6 ("davinci: omapl138_lcdk: increase PLL0 frequency")
    changed the PLL0 frequency to 456MHz, which is needed for the LCDC IP
    block. However, in doing so, it caused the PLLOUT clock to be outside
    of the allowable specifications given in the OMAP-L138 data sheet. (It
    says PLLOUT must be 600MHz max). It also uses a PLLM value outside of
    the range given in the TRM (it says PLLM must in the range 0 to 0x1f).

    So here is what we have currently:

    PLLOUT = 24 / (0 + 1) * (37 + 1) = 912MHz (out of spec)
    ^ ^ ^
    CLKIN PREDIV PLLM (out of spec)

    input to PLLDIVn = 912 / (1 + 1) = 456MHz (desired result)
    ^ ^
    PLLOUT POSTDIV

    This changes the PLLM value to 18 and the POSTDIV value to 0 so that
    PLLOUT is now within specification but we still get the desired
    result.

    PLLOUT = 24 / (0 + 1) * (18 + 1) = 456MHz (within spec)
    ^ ^ ^
    CLKIN PREDIV PLLM

    input to PLLDIVn = 456 / (0 + 1) = 456MHz (desired result)
    ^ ^
    PLLOUT POSTDIV

    On the NIOS2 and Xtensa architectures, we do not have

    Having this as a 'default y' is rather annoying because it doesn't
    actually compile unless other options are defined in the board header:

    ../cmd/bootm.c: In function 'do_imls_nor':
    ../cmd/bootm.c:330:7: error: 'CONFIG_SYS_MAX_FLASH_BANKS' undeclared (first use in this function); did you mean 'CONFIG_SYS_MAX_FLASH_SECT'?
    i < CONFIG_SYS_MAX_FLASH_BANKS; ++i, ++info) {

    Make it 'default n' so people who develop new boards that start from a
    blank defconfig have one less compilation failure to debug.

  • b44b30260   printk: collect printk stuff into <linux/printk.h> with loglevel support ... Browse Code »

    When we import code from Linux, with regular re-sync planned, we want
    to use printk() and pr_*(). U-Boot does not support them in a clean
    way. So, people end up with local macros, or compat headers here and
    there, then we occasionally see build errors of definition conflicts.

    We have include/linux/compat.h, but putting all sorts of unrelated
    things into a single header is just a temporal workaround. Hence this
    patch, to find the best home for all printk variants. If you want to
    use printk() and friends, please include . This header
    is self-contained, and pulls in only a few headers.

    When I was testing this clean-up, I noticed the image size exceeded
    its platform limit on some boards. This is because all pr_*() that
    were previously defined as no-op in include/linux/mtd/mtd.h (unless
    CONFIG_MTD_DEBUG is set), are now enabled.

    To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
    The concept is similar to the kernel parameter "loglevel". (Actually,
    the Kconfig help message was taken from kernel-paremeter.txt of Linux)
    Messages with a loglevel smaller than console loglevel will be printed.

    The difference is the loglevel is build-time determined. To save the
    image size, lower priority pr_*() are compiled out. I set the default
    of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
    are compiled in.

    I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

    20

    This converts the following to Kconfig:
    CONFIG_ENV_IS_IN_MMC
    CONFIG_ENV_IS_IN_NAND
    CONFIG_ENV_IS_IN_UBI
    CONFIG_ENV_IS_NOWHERE

    In fact this already exists for sunxi as a 'choice' config. However not
    all the choices are available in Kconfig yet so we cannot use that. It
    would lead to more than one option being set.

    In addition, one purpose of this series is to allow the environment to be
    stored in more than one place. So the existing choice is converted to a
    normal config allowing each option to be set independently.

    There are not many opportunities for Kconfig updates to reduce the size of
    this patch. This was tested with

    ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC

    And then manual updates. This is because for CHAIN_OF_TRUST boards they
    can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
    now.
