    i.MX8MQ B2 is using same value in OCOTP_READ_FUSE_DATA like B1, so
    we have to check the ROM verision to distinguish the revision.

    As we have checked the B1 rev for sticky bits work around in
    secure boot. So it won't apply on B2.

    There are 3 part numbers for 11x11 i.MX8MNano with different core number
    configuration: UltraLite Quad/Dual/Solo

    Comparing with i.MX8MN Lite parts, they have MIPI DSI disabled. So
    checking the MIPI DSI disable fuse to recognize these parts.

    According to datasheet, there are totally 6 variant parts for imx8mn:
    Quad, Dual, Solo with core number changed.
    QuadLite, DualLite, SoloLite with core number changed and GPU disabled.

    Add the support for these variant parts
    1. Recognize the variant parts according to fuse
    2. Power down disabled cores
    3. Remove the cores node and disable GPU node from kernel DTB before
    entering kernel.
    4. Since the mscale dummy id has been used out, increase one more bit
    (bit 8) for cpu id.

    Since commit 8891410c729b ("MLK-19848 mx6dq: Fix chip version issue for
    rev1.3") it's not possible to call the HAB API functions on i.MX6DQ
    SoC Rev 1.3:

    Authenticate image from DDR location 0x12000000...
    undefined instruction
    pc : [] lr : []
    reloc pc : [] lr : []
    sp : 8ef444a8 ip : 126e8068 fp : 8ff59aa8

    Flags: nzCv IRQs off FIQs off Mode SVC_32
    Resetting CPU ...

    resetting ...

    The hab.h code is defining the HAB API base address according to the
    old SoC revision number, thus failing when calling the HAB API
    authenticate_image() function.

    Fix this issue by using mx6dq rev 1.3 instead of mx6dq rev 1.5.

    print_cpuinfo() in board init code requires uclass CPU driver,
    add it to be able to display CPU info when CONFIG_DISPLAY_CPUINFO
    option is enabled. CPU node in DT will have to include 'clocks'
    and 'u-boot,dm-pre-reloc' properties for generic print_cpuinfo()
    to work as expected. The driver outputs info for i.MX8QXP Rev A
    and Rev B CPUs.

  • 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.

    Implement soc level functions to get cpu rev, reset cause, enable cache,
    etc. We will disable the wdog and init clocks in s_init at very early u-boot
    phase.

    Since the we are seeking the way to get chip id for mx7ulp, the get_cpu_rev
    is hard coded to a fixed value. This may change in future.

    Reuse some code in imx-common.

    Since we need to support runtime check for different drivers, we need
    to add get_cpu_rev for vf610, otherwise there will be build errors.

    This patch introduces a dummy CPU id which is not read from chip
    silicon. Later when we can get the real id from chip, can fix the
    value of MXC_CPU_VF610 then.
