    Since commit c98b47f1ff60 ("MLK-22749 imx8mq: Add workaround to fix sticky
    bits lock up") it's not possible to build i.MX8MM and i.MX8MN targets with
    CONFIG_SECURE_BOOT enabled:

    CC cmd/version.o
    arch/arm/mach-imx/imx8m/soc.c:326:23: error: ‘CONFIG_IMX_UNIQUE_ID’ undeclared \
    (first use in this function); did you mean ‘CONFIG_IMX_VIDEO_SKIP’?
    if (!is_uid_matched(CONFIG_IMX_UNIQUE_ID))
    ^~~~~~~~~~~~~~~~~~~~

    The OCOTP sticky bit workaround is only needed for i.MX8MQ devices, other devices
    should not build the secure_lockup() function.

    Add CONFIG_IMX8MQ to the conditional compilation to avoid such issue.

    When enabled randomizer during ECC reading, the controller reported it's
    erased page. Checking zero count will cause data get modified to all
    0xFF. Stop checking during randomizer to workaround this issue.

  • 40419231e   MLK-22755 mx7ulp: wdog: Wait for WDOG unlock and reconfiguration to complete ... Browse Code »

    According to i.MX7ULP Reference Manual we should wait for WDOG unlock
    and reconfiguration to complete.

    Section "59.5.3 Configure Watchdog" provides the following example:

    DisableInterrupts; //disable global interrupt
    WDOG_CNT = 0xD928C520; //unlock watchdog
    while(WDOG_CS[ULK]==0); //wait until registers are unlocked
    WDOG_TOVAL = 256; //set timeout value
    WDOG_CS = WDOG_CS_EN(1) | WDOG_CS_CLK(1) | WDOG_CS_INT(1) |
    WDOG_CS_WIN(0) | WDOG_CS_UPDATE(1);
    while(WDOG_CS[RCS]==0); //wait until new configuration takes effect
    EnableInterrupts; //enable global interrupt

    Update U-Boot WDOG driver to align with i.MX7ULP reference manual.

  • 45d3f14c6   MA-15339-1 load ramdisk in boot image to do first stage mount ... Browse Code »

    With Android10 code, to build GSI image for devices launching with
    Android10, the target should be "aosp_$arch-user". Google releases GSI
    images is so built in user mode.

    To do CTS-on-GSI test, a debug ramdisk containing .prop file to enable
    adb root permission and GSI keys to verify the GSI image is needed, this
    ramdisk is in boot image. so ramdisk in boot image need to be loaded by
    uboot even in non-recovery mode.

    To save boot time, only standard Android use ramdisk to boot up Android,
    Android Auto keeps the original way: kernel be responsible for verify
    and mount system partition. Let the customers to decide whether to use
    recovery ramdisk to boot the system. and under this condition, user-debug
    Android Auto GSI image need to be used for VTS-on-GSI test.

    when use ramdisk to bootup Android, info provided by "dm=" bootarg is
    not used by kernel to setup dm-verity, so it is removed from the
    bootargs. The 4.19 kernel used together with this uboot does not handle
    "skip_initramfs", so it's also removed.

  • 653c84e3e   MLK-22748 imx8mn: Fix flexspi flash SCLK violation ... Browse Code »

    Current flexspi driver enables the Quad DTR read, so the measured
    100Mhz SCLK is actually for DTR mode not SDR. However, according to
    MT25QU256ABA datasheet, this flash only supports max DTR at 90Mhz and
    max SDR at 166Mhz. It means current clock setting violate the flash
    spec. So change back the flexspi clock to align with imx8mm.

  • 443b88f33   MLK-22749 imx8mq: Add workaround to fix sticky bits lock up ... Browse Code »

    On B1 chips with HAB v4.4, the sticky bits are not locked up in
    HAB closed mode. We introduce a workaround in SPL to lock up
    these bits and clear Manufacturing Protection Private Key for
    secure boot.

    For field return case, user has to build a SPL with
    CONFIG_SECURE_STICKY_BITS_LOCKUP=n and set CONFIG_IMX_UNIQUE_ID to
    part's unique id. When the UID check is passed, sticky bits are not
    lockup and users can burn field return fuse. Otherwise the boot will
    stop.

  • 5f20cc02b   MLK-22743 mx7ulp: Update unlock and refresh sequences in sWDOG driver ... Browse Code »

    According to i.MX7ULP Reference Manual the second word write for both
    UNLOCK and REFRESH operations must occur in maximum 16 bus clock.

    The current code is using writel() function which has a DMB barrier to
    order the memory access. The DMB between two words write may introduce
    some delay in certain circumstance, causing a WDOG timeout due to 16 bus
    clock window requirement.

    Replace writel() function by __raw_writel() to achieve a faster memory
    access and avoid such issue.

  • ddc607692   MLK-22622 imx8m: Add Workaround for ROM SError issue ... Browse Code »

    ROM SError happens on two cases:

    1. ERR050342, on iMX8MQ HDCP enabled parts ROM writes to GPV1 register, but
    when ROM patch lock is fused, this write will cause SError.

    2. ERR050350, on iMX8MQ/MM/MN, when the field return fuse is burned, HAB
    is field return mode, but the last 4K of ROM is still protected and cause SError.

    Since ROM mask SError until ATF unmask it, so then ATF always meets the exception.
    This patch works around the issue in SPL by enabling SPL Exception vectors table
    and the SError exception, take the exception to eret immediately to clear the SError.
