  • 47870afab   initcall: Move to inline function ... Browse Code »

    The board_r init function was complaining that we are looping through
    an array, calling all our tiny init stubs sequentially via indirect
    function calls (which can't be speculated, so they are slow).

    The solution to that is pretty easy though. All we need to do is inline
    the function that loops through the functions and the compiler will
    automatically convert almost all indirect calls into direct inlined code.

    With this patch, the overall code size drops (by 40 bytes on riscv64)
    and boot time should become measurably faster for every target.

  • 51c2345bd   Roll CRC16-CCITT into the hash infrastructure ... Browse Code »

    The CRC16-CCITT checksum function is useful for space-constrained
    applications (such as obtaining a checksum across a 2KBit or 4KBit
    EEPROM) in boot applications. It has not been accessible from boot
    scripts until now (due to not having a dedicated command and not being
    supported by the hash infrstructure) limiting its applicability
    outside of custom commands.

    This adds the CRC16-CCITT (poly 0x1021, init 0x0) algorithm to the
    list of available hashes and adds a new crc16_ccitt_wd_buf() to make
    this possible.

  • 9f9ce3c36   tpm: prepare introduction of TPMv2.x support in Kconfig ... Browse Code »

    Because both major revisions are not compatible at all, let's make them
    mutually exclusive in Kconfig. This way we will be sure, when using a
    command or a library function that it is supported by the right
    revision.

    Current drivers are currently prefixed by "tpm_", we will prefix TPMv2.x
    files by "tpm2_" to make the distinction without moving everything.

    The Kconfig menu about TPM drivers is now divided into two sections, one
    for each specification. Compliant drivers with one specification will
    only show up if this specification _only_ has been selected, otherwise a
    comment is displayed.

    Once a driver is selected by the user, it selects automatically a
    boolean value, that is needed in order to activate the TPM commands.
    Selecting the TPM commands will automatically select the right
    command/library files.

  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

  • 05ef48a24   efi_driver: EFI block driver ... Browse Code »

    This patch provides
    * a uclass for EFI drivers
    * a EFI driver for block devices

    For each EFI driver the uclass
    * creates a handle
    * adds the driver binding protocol

    The uclass provides the bind, start, and stop entry points for the driver
    binding protocol.

    In bind() and stop() it checks if the controller implements the protocol
    supported by the EFI driver. In the start() function it calls the bind()
    function of the EFI driver. In the stop() function it destroys the child
    controllers.

    The EFI block driver binds to controllers implementing the block io
    protocol.

    When the bind function of the EFI block driver is called it creates a
    new U-Boot block device. It installs child handles for all partitions and
    installs the simple file protocol on these.

    The read and write functions of the EFI block driver delegate calls to the
    controller that it is bound to.

    A usage example is as following:

    U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
    exposes a handle with the block IO protocol. It calls ConnectController.

    Now the EFI block driver installs the partitions with the simple file
    protocol.

    iPXE uses the simple file protocol to load Grub or the Linux Kernel.

    Commit 94e3c8c4fd7b ("crypto/fsl - Add progressive hashing support
    using hardware acceleration.") created entries for CONFIG_SHA1,
    CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL.
    However, no defconfig has migrated to it. Complete the move by first
    adding additional logic to various Kconfig files to select this when
    required and then use the moveconfig tool. In many cases we can select
    these because they are required to implement other drivers. We also
    correct how we include the various hashing algorithms in SPL.

    This commit was generated as follows (after Kconfig additions):

    [1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL
    [2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL

    Note:
    We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously
    because there is dependency between them.
