  • 1811a928c   Move most CONFIG_HAVE_BLOCK_DEVICE to Kconfig ... Browse Code »

    config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE
    based on a list of enabled options. Moving HAVE_BLOCK_DEVICE to
    Kconfig allows us to drastically shrink the logic in
    config_fallbacks.h

    config_fallback.h has some logic that checks a variety of options
    and selects LIB_UUID if it hasn't already been selected. This
    will all LIB_UUID in Kconfig and select this option for the list
    of options to allow us to remove the logic from fallbacks

  • 6698bb343   efi: Conflict efi_loader with different stub bitness ... Browse Code »

    We have 2 users of the EFI headers: efi_loader and the EFI stub. Efi_loader
    always expects that the bitness of the definitions it uses is identical to
    the execution.

    The EFI stub however allows to run x86_64 U-Boot on 32bit EFI and the other
    way around, so it allows for different bitness of EFI definitions and U-Boot
    environment.

    This patch explicitly requests via Kconfig that efi_loader can only be enabled
    if the bitness is identical. Because we can run efi_loader on x86_64 without
    EFI stub enabled, it also ensures that this case propagates the correct ABI
    constraints.

  • 58ad86288   x86: Enable EFI loader support ... Browse Code »

    Enable this so that EFI applications (notably grub) can be run under U-Boot
    on x86 platforms.

    At present the 'hello world' EFI application is not supported for the
    qemu-x86_efi_payload64 board. That board builds a payload consisting of a
    64-bit header and a 32-bit U-Boot, which is incompatible with the way the
    EFI loader builds its EFI application. The following error is obtained:

    x86_64-linux-ld.bfd: i386 architecture of input file
    `lib/efi_loader/helloworld.o' is incompatible with i386:x86-64 output

    This could be corrected with additional Makefile rules. For now, this
    feature is disabled for that board.

  • 456ca6ba0   efi_loader: fix depends on line of EFI_LOADER ... Browse Code »

    This line is shown as

    depends on (ARM64 ||\302\240ARM) && OF_LIBFDT

    on my Emacs. Use ASCII characters only.

    Assuming it is (ARM64 || ARM), remove the redundancy.
    Unlike Linux, CONFIG_ARM includes CONFIG_ARM64 in U-Boot.

  • 51735ae0e   efi_loader: Add bounce buffer support ... Browse Code »

    Some hardware that is supported by U-Boot can not handle DMA above 32bits.
    For these systems, we need to come up with a way to expose the disk interface
    in a safe way.

    This patch implements EFI specific bounce buffers. For non-EFI cases, this
    apparently was no issue so far, since we can just define our environment
    variables conveniently.

    Now that we have all the bits and pieces ready for EFI payload loading
    support, hook them up in Makefiles and KConfigs so that we can build.
