3462b55d17 imx8mp: Set default SNSR25C for TMU probe1
So far u-boot only load SNSR25C for TMU main probe (probe 0). However,
kernel enables two probes. So it also needs to set default SNSR25C of
TCALIV1 for blank samples.

ebb9aab318 imx: load calibration parameters from fuse for i.MX8MP
i.MX8MP thermal which has two probes and supports temperature range
from -40 to 125.  The driver still uses default 1p HW
calibration at 25C and loads calibration parameters from fuse.

94c693d782 imx: i.MX8MN: Enable loading TASR and TCALIV from fuse
Like iMX8MM, iMX8MN also needs SW to load TMU TASR and TCALIV registers
value from fuse before enabling TMU calibration. Otherwise the calibration
is not exact.

70487ff386 imx8mm: Load fuse for TMU TCALIV and TASR
On iMX8MM, the default value of TMU registers TCALIV and TASR need
be loaded from fuse. HW won't do this, it expect SW loads them before
using TMU.

7247974643 imx8m: Enable WDOG_B for timeout
When doing reset_cpu, in normal case the WDOG_B outputs immediately
after we clean WDA bit. But on mscale, the WDOG_B may be later than
internal reset, and cause PMIC not reset. As we enabled the SD3.0
support, the PMIC must be reset to reset SD card.

Change the reset_cpu to enable the WDOG_B for timeout as well, and set
WDOG timeout to 1s.

712a341c76 imx8mq: Set ARM core clock directly from ARM PLL
For ARM core clock, there are two input branches, and can select via mux:
one from ARM PLL directly, second from CCM A53 clock root.

Currently we are using second branch. But IC confirmed the CCM A53 root
signoff timing is 1Ghz, so we should switch to input from ARM PLL directly.

This patch fixes the CORE SEL slice configuration and switch ARM clock
to ARM PLL.

are factory fused to properly boot from their on-module eMMC. U-Boot

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet
- GPIOs
- I2C

Boot sequence is:

6a4b07e086 imx8m: fix rom version check to unbreak some B0 chips
Recently the version check was improved to be able to determine that
we're running on SoC revision 2.1.  A check for B0 was tightened so
that it now must equal 0x20 instead of being bigger than 0x20.  On
some B0 chips the value returned is 0x1020 instead of 0x20.  This
means even though it's B0, the check will fail and code relying on
the correct chip revision will make wrong decisions.  There is no
documentation of those bits, but it seems that NXP always uses a
byte to encode the revision.  Thus remove the upper bits to fix the
regression.

the clock code of i.MX8MM, but i.MX8MN has different CCM root
configurations, so need a separate root entry.

59efa6b52b imx8m: Fix MMU table issue for OPTEE memory
When running with OPTEE, the MMU table in u-boot does not remove the OPTEE
memory from its settings. So ARM speculative prefetch in u-boot may access
that OPTEE memory. Due to trust zone is enabled by OPTEE and that memory
is set to secure access, then the speculative prefetch will fail and cause
various memory issue in u-boot.
The fail address register and int_status register in trustzone has logged
that speculative access from u-boot.
