  • d4150ca6d   Provide a generic io.h & address mapping functions ... Browse Code »

    Most architectures currently supported by U-Boot use trivial
    implementations of map_to_physmem & virt_to_phys which simply cast a
    physical address to a pointer for use a virtual address & vice-versa.
    This results in a lot of duplicate implementations of these mapping
    functions.

    The set of functions provided by different architectures also differs,
    with some having implementations of phys_to_virt & others not. A later
    patch will make use of phys_to_virt in architecture-neutral code, and so
    requires that it be provided for all architectures.

    This patch introduces an asm-generic/io.h which provides generic
    implementations of address mapping functions, allowing the duplication
    of them between architectures to be removed. Once architectures are
    converted to make use of this generic header it will also ensure that
    all of phys_to_virt, virt_to_phys, map_physmem & unmap_physmem are
    provided. The 2 families of functions differ in that map_physmem may
    create dynamic mappings whilst phys_to_virt may not & therefore is more
    limited in scope but doesn't require information such as a length &
    flags.

    This patch doesn't convert any architectures to make use of this generic
    header - later patches in the series will do so.

  • 5e44489bc   efi_loader: rename __efi_hello_world_* ... Browse Code »

    In scripts/Makefile.lib we build section including helloworld.efi.
    This allows to load the EFI binary with command 'bootefi hello'.

    scripts/Makefile.lib contains explicit references to strings
    containing helloworld and hello_world. This makes it impossible
    to generalize the coding to accomodate additional built in
    EFI binaries.

    Let us rename the variables __efi_hello_world_* to
    __efi_helloworld_*.

  • 00caae6d4   env: Rename getenv/_f() to env_get() ... Browse Code »

    We are now using an env_ prefix for environment functions. Rename these
    two functions for consistency. Also add function comments in common.h.

    Quite a few places use getenv() in a condition context, provoking a
    warning from checkpatch. These are fixed up in this patch also.

  • f1896c45c   spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN ... Browse Code »
    23

    Some platforms have very limited SRAM to run SPL code, so there may
    not be the same amount space for a malloc pool before relocation in
    the SPL stage as the normal U-Boot stage.

    Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
    so the size of pre-relocation malloc pool can be configured memory
    space independently.

  • 907208c45   powerpc: Partialy restore core of mpc8xx ... Browse Code »
    17

    CS Systemes d'Information (CSSI) manufactures 8xx boards for
    critical communication systems. Those boards have been
    running U-Boot since 2010 and will have to be maintained
    until at least 2027.

    commit 5b8e76c35ec312a3f73126bd1a2d2c0965b98a9f
    ("powerpc, 8xx: remove support for 8xx") orphaned those boards
    by removing support for the mpc8xx CPU.

    This commit partially restores support for the 8xx, with the
    following limitations:
    - Restores support for MPC866 and MPC885 only
    - Does not restore IDE, PCMCIA, I2C, USB
    - Does not restore examples
    - Does not restore POST
    - Does not restore Ethernet on SCC
    - Does not restore console on SCC
    - Does not restore bedbug and kgdb support

    As the 866 and 885 do not support the following features,
    they are not restored either:
    - VIDEO / LCD
    - RTC clock

    The CPM uCODE patch is not restored either, because:
    - 866 and 885 already have support for I2C and SPI relocation
    without a uCODE patch
    - relocation of SMC, I2C or SPI is only needed for using SCCs
    for Ethernet or QMC

    The dynamic setup/calculation of clocks is removed, we
    expect the target being use with the clock and PLPRCR register
    defined in the configuration.
    All the clock settings for 8xx prior to 866 is removed as
    well as we now only support 866 and 885.

    This code is mature and addresses mature boards. Therefore
    all code enclosed in '#if 0/#endif' and '#if XX_DEBUG/#endif'
    is unneeded.

    The following files are not restored by this patch:

    - arch/powerpc/cpu/mpc8xx/bedbug_860.c
    - arch/powerpc/cpu/mpc8xx/fec.h
    - arch/powerpc/cpu/mpc8xx/kgdb.S

    - post/cpu/mpc8xx/uart.c
    - post/cpu/mpc8xx/usb.c
    - post/cpu/mpc8xx/watchdog.c

    Some of the restored files are not located in a proper location.
    In order to keep traceability of the changes, they will be
    moved to their correct location and moved to Kconfig in a
    followup patch.

    This patch also declares CSSI as point of contact for the update
    of the 8xx platform, as those boards are the only ones still
    being maintained on the 8xx area. A later patch will add
    those boards to the tree.

  • daab59ac0   avr32: Retire AVR32 for good ... Browse Code »

    AVR32 is gone. It's already more than two years for no support in Buildroot,
    even longer there is no support in GCC (last version is heavily patched 4.2.4).

    Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully).

    There is no good point to keep this support in U-Boot either.

  • b383d6c05   bootstage: Convert to use malloc() ... Browse Code »
    46

    At present bootstage uses the data section of the image to store its
    information. There are a few problems with this:

    - It does not work on all boards (e.g. those which run from flash before
    relocation)
    - Allocated strings still point back to the pre-relocation data after
    relocation

    Now that U-Boot has a pre-relocation malloc() we can use this instead,
    with a pointer to the data in global_data. Update bootstage to do this and
    set up an init routine to allocate the memory.

    Now that we have a real init function, we can drop the fake 'reset' record
    and add a normal one instead.

    Note that part of the problem with allocated strings remains. They are
    reallocated but this will only work where pre-relocation memory is
    accessible after relocation.

  • 340f418ac   spl: Add spl_early_init() ... Browse Code »
    23

    At present malloc_base/_limit/_ptr are not initialised in spl_init() when
    we call spl_init() in board_init_f(). This is due to a recent change aimed
    at avoiding overwriting the malloc area set up on some boards by
    spl_relocate_stack_gd().

    However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now
    skip setting up the memory area in spl_init() which is obviously wrong.

    To fix this, add a new function spl_early_init() which can be called in
    board_init_f().

  • 53ecdfb92   dm: gpio: Add methods for open drain setting ... Browse Code »

    Certain GPIO devices have the capability to switch their GPIOs into
    open-drain mode, that is, instead of actively driving the output
    (Push-pull output), the pin is connected to the collector (for a NPN
    transistor) or the drain (for a MOSFET) of a transistor, respectively.
    The pin then either forms an open circuit or a connection to ground,
    depending on the state of the transistor.

    This patch adds functions to the GPIO uclass to switch GPIOs to
    open-drain mode on devices that support it.

    This patch adds a common implementation of this type of parsing

    routine.

    This will allow removal of the driver-specific versions in a
    handful of drivers and simplify the addition of new drivers.

    Before relocation we need to reserve memory for the video driver frame
    buffers so that they can use this memory when they start up (after
    relocation). Add a call to the uclass to permit this.

    The current top and bottom of the region is stored in global_data so that
    it can be checked post-relocation to ensure enough memory is available. No
    video device should be probed before relocation.

  • e81495224   Reserve secure memory ... Browse Code »

    Secure memory is at the end of memory, separated and reserved
    from OS, tracked by gd->secure_ram. Secure memory can host
    MMU tables, security monitor, etc. This is different from PRAM
    used to reserve private memory. PRAM offers memory at the top
    of u-boot memory, not necessarily the real end of memory for
    systems with very large DDR. Using the end of memory simplifies
    MMU setup and avoid memory fragmentation.

    "bdinfo" command shows gd->secure_ram value if this memory is
    marked as secured.
