    Enable "optee_rpmb" command to write/read named persistent values
    created on RPMB by opening session with OPTEE AVB TA.
    This provides easy test for establishing a session with OPTEE
    TA and storage of persistent data in MMC RPMB.

    It includes following subcommands:

    optee_rpmb read_pvalue - read persistent values on rpmb via OPTEE AVB TA
    optee_rpmb write_pvalue - write persistent values on rpmb via OPTEE AVB TA

  • 7be64b885   cmd: bootefi: Parse reserved-memory node from DT ... Browse Code »

    Currently, bootefi only parses memory reservation block to setup
    EFI reserved memory mappings. However, it doesn't parse the
    reserved-memory[1] device tree node that also can contain the
    reserved memory regions.

    Add capability to parse reserved-memory node and update the EFI memory
    mappings accordingly.

    Addresses in the sandbox's device tree are in the sandbox's virtual address
    space. If we want to compare memory reservations in the device-tree with
    the output of 'efidebug memmap', we need to convert back to this address
    space.

    12

    Some memory reservations are made in ft_board_setup(). Ensure that we
    create reserved memory map entries after ft_board_setup().

    The downside of this patch is that if bootefi is called multiple times with
    an devicetree argument superfluous reservations for the old copies of the
    device tree will exist. But that is still better than missing a reservation.

    Deleting the superfluous reservations is not possible because reservations
    in the memory map are rounded to page size and may be coallesced.

  • ec80b4735   efi_loader: Implement FileLoad2 for initramfs loading ... Browse Code »

    Following kernel's proposal for an arch-agnostic initrd loading
    mechanism [1] let's implement the U-boot counterpart.
    This new approach has a number of advantages compared to what we did up
    to now. The file is loaded into memory only when requested limiting the
    area of TOCTOU attacks. Users will be allowed to place the initramfs
    file on any u-boot accessible partition instead of just the ESP one.
    Finally this is an attempt of a generic interface across architectures
    in the linux kernel so it makes sense to support that.

    The file location is intentionally only supported as a config option
    argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security.
    Although U-boot is not responsible for verifying the integrity of the
    initramfs, we can enhance the offered security by only accepting a
    built-in option, which will be naturally verified by UEFI Secure Boot.
    This can easily change in the future if needed and configure that via ENV
    or UEFI variable.

    At present dm/device.h includes the linux-compatible features. This
    requires including linux/compat.h which in turn includes a lot of headers.
    One of these is malloc.h which we thus end up including in every file in
    U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
    which needs to use the system malloc() in some files.

    Move the compatibility features into a separate header file.

    The command tpm (and tpm2) search the tpm and use it.
    On sandbox, there are two tpm (tpm 1.x and tpm 2.0).
    So the command tpm and tpm2 are always executed with
    the first tpm (tpm 1.x), and the command tpm2 always
    fails.

    This add a subcommand device to command tpm and
    command tpm2. Then the command tpm and tpm2 use
    the device selected with the subcommand device.

    To be compatible with previous behaviour, if the
    subcommand device is not used before a tpm (or tpm2)
    command, the device 0 is selected.

    where dtb is taken from boot.img (as v2 incorporated dtb inside of

    boot.img in scripting manner, and then apply needed dtbo's (from "dtbo"
    partition) on top of that, providing then the resulting image to bootm
    command in order to boot the Android.

    Also right now this command has the sub-command to get an address and
    size of recovery dtbo from recovery image (for non-A/B devices only,
    see [1,2] for details).

    It can be tested like this:

    => mmc dev 1

  • b852cca8f   pmic: allow dump command for non contiguous register maps ... Browse Code »

    Some PMICs (such as the DA9063) have non-contiguous register maps.
    Attempting to read the non implemented registers returns an error
    rather than a dummy value which causes 'pmic dump' to terminate
    prematurely.

    Fix this by allowing the PMIC driver to return -ENODATA for such
    registers, which will then be displayed as '--' by pmic dump.

    Use a single error code rather than any error code so that
    we can distinguish between a hardware failure reading the PMIC
    and a non implemented register known to the driver.

  • b1b147f2b   cmd: mtd: solve bad block support in erase command ... Browse Code »

    This patch modify the loop in mtd erase command to erase one by one
    the blocks in the requested area.

    It solves issue on "mtd erase" command on nand with existing bad block,
    the command is interrupted on the first bad block with the trace:
    "Skipping bad block at 0xffffffffffffffff"

    In MTD driver (nand/raw), when a bad block is present on the MTD
    device, the erase_op.fail_addr is not updated and we have the initial
    value MTD_FAIL_ADDR_UNKNOWN = (ULL)-1.

    This case seems normal in nand_base.c:nand_erase_nand(),
    we have the 2 exit cases during the loop:

    1/ we have a bad block (nand_block_checkbad)
    instr->state = MTD_ERASE_FAILED
    loop interrupted (goto erase_exit)

    2/ if block erase failed (status & NAND_STATUS_FAIL)
    instr->state = MTD_ERASE_FAILED;
    instr->fail_addr =
    ((loff_t)page << chip->page_shift);
    loop interrupted (goto erase_exit)

    So erase_op.fail_addr can't be used if bad blocks were present
    in the erased area; we need to use mtd_erase only one block to detect
    and skip these existing bad blocks (as it is done in nand_util.c).
