  • 871a57bb8   common/cmd_bootm: extend do_bootm_vxworks to support the new VxWorks boot interface. ... Browse Code »

    The next version VxWorks adopts device tree (for PowerPC and ARM) as its hardware
    description mechanism. For PowerPC, the boot interface conforms to
    the ePAPR standard, which is:

    void (*kernel_entry)(ulong fdt_addr,
    ulong r4 /* 0 */,
    ulong r5 /* 0 */,
    ulong r6 /* EPAPR_MAGIC */, ulong r7 /* IMA size */,
    ulong r8 /* 0 */, ulong r9 /* 0 */)

    For ARM, the boot interface is:

    void (*kernel_entry)(void *fdt_addr)

  • ba6a16981   ARM: add SMP support for non-secure switch ... Browse Code »

    Currently the non-secure switch is only done for the boot processor.
    To enable full SMP support, we have to switch all secondary cores
    into non-secure state also.

    So we add an entry point for secondary CPUs coming out of low-power
    state and make sure we put them into WFI again after having switched
    to non-secure state.
    For this we acknowledge and EOI the wake-up IPI, then go into WFI.
    Once being kicked out of it later, we sanity check that the start
    address has actually been changed (since another attempt to switch
    to non-secure would block the core) and jump to the new address.

    The actual CPU kick is done by sending an inter-processor interrupt
    via the GIC to all CPU interfaces except the requesting processor.
    The secondary cores will then setup their respective GIC CPU
    interface.
    While this approach is pretty universal across several ARMv7 boards,
    we make this function weak in case someone needs to tweak this for
    a specific board.

    The way of setting the secondary's start address is board specific,
    but mostly different only in the actual SMP pen address, so we also
    provide a weak default implementation and just depend on the proper
    address to be set in the config file.

  • b2e16a85a   Add trace library ... Browse Code »

    Add a library which supports tracing of execution using built-in gcc
    features and a microsecond timer. This can be used to record a list of
    function which are executed, along with a timestamp for each. Later
    this information can be sent to the host for processing.

  • 063ae006a   main: Separate out the two abortboot() functions ... Browse Code »

    There are two implementations of abortboot(). Turn these into two separate
    functions, and create a single abortboot() which calls either one or the
    other.

    Also it seems that nothing uses abortboot() outside main, so make it static.

    At this point there is no further use of CONFIG_MENU in main.c.

    This seems to be a common function for several architectures, so create
    a common function rather than duplicating the code in each arch.

    Also make an attempt to avoid introducing #ifdefs in the new code, partly
    by removing useless #ifdefs around function declarations in the image.h
    header.

  • 781adb571   sandbox: Provide a way to map from host RAM to U-Boot RAM ... Browse Code »

    In many cases, pointers to memory are passed around, and these pointers
    refer to U-Boot memory, not host memory. This in itself is not a
    problem.

    However, in a few places, we cast that pointer back to a ulong (being
    a U-Boot memory address). It is possible to convert many of these cases
    to avoid this. However there are data structures (e.g. struct
    bootm_headers) which use pointers. We could with a lot of effort adjust
    the structs and all code that uses them to use ulong instead of pointers.

    This seems like an unacceptable cost, since our objective with sandbox
    is to minimise the impact on U-Boot code while maximising the features
    available to sandbox.

    Therefore, create a map_to_sysmem() function which converts from a
    pointer to a U-Boot address. This can be used sparingly when needed.

  • 4213fc291   sandbox: Add un/map_sysmen() to deal with sandbox's ram_buf ... Browse Code »

    Sandbox doesn't actually provide U-Boot access to the machine's physical
    memory. Instead it provides a RAM buffer of configurable size, and all
    memory accesses are within that buffer. Sandbox memory starts at 0 and
    is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer
    might produce unpredictable results in the event of an error, and would
    expose the host machine's memory architecture to the sandbox U-Boot.

    Most U-Boot functions assume that they can just access memory at given
    address. For sandbox this is not true.

    Add a map_sysmem() call which converts a U-Boot address to a system
    address. In most cases this is a NOP, but for sandbox it returns a
    pointer to that memory inside the RAM buffer.

    To get a U-Boot feature to work correctly within sandbox, you should call
    map_sysmem() to get a pointer to the address, and then use that address for
    any U-Boot memory accesses.

  • 15a33e49d   Add option to display customised memory information ... Browse Code »

    Some boards want to report more than just memory size. For example, it
    might be useful to display the memory type (DDR2, DDR3) or manufacturer.

    Add a weak function to support this requirement, accessed through a new
    'meminfo' command.

    Any example of the DRAM: output is below, just for illustration:

    SMDK5250 # meminfo

  • e05e5de7f   arm: move C runtime setup code in crt0.S ... Browse Code »

    Move all the C runtime setup code from every start.S
    in arch/arm into arch/arm/lib/crt0.S. This covers
    the code sequence from setting up the initial stack
    to calling into board_init_r().

    Also, rewrite the C runtime setup and make functions
    board_init_*() and relocate_code() behave according to
    normal C semantics (no jumping across the C stack any
    more, etc).

    Some SPL targets had to be touched because they use
    start.S explicitly or for some reason; the relevant
    maintainers and custodians are cc:ed.

  • eef1cf2d5   include/linux/byteorder: import latest endian definitions from linux ... Browse Code »

    u-boot's byteorder headers did not contain endianness attributions
    for use with sparse, causing a lot of false positives. Import the
    kernel's latest definitions, and enable them by including compiler.h
    and types.h. They come with 'const' added for some swab functions, so
    fix those up, too:

    include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]

    Also, note: u-boot's historic __BYTE_ORDER definition has been
    preserved (for the time being at least).

    We also remove ad-hoc barrier() definitions, since we're including
    compiler.h in files that hadn't in the past:

    macb.c:54:0: warning: "barrier" redefined [enabled by default]

    In addition, including compiler.h in byteorder changes the 'noinline'
    definition to expand to __attribute__((noinline)). This fixes
    arch/powerpc/lib/bootm.c:

    bootm.c:329:16: error: attribute '__attribute__': unknown attribute
    bootm.c:329:16: error: expected ')' before '__attribute__'
    bootm.c:329:25: error: expected identifier or '(' before ')' token

    powerpc sparse builds yield:

    include/common.h:356:22: error: marked inline, but without a definition

    the unknown-reason inlining without a definition is considered obsolete
    given it was part of the 2002 initial commit, and no arm version was
    'fixed.'

    also fixed:
    ydirectenv.h:60:0: warning: "inline" redefined [enabled by default]

    and:
