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.

calibration at 25C and loads calibration parameters 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.

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.

imx8m has the only implementation of reset_cpu() which does not ignore
the addr parameter and instead gives it some meaning as the base address
of watchdog registers. This breaks convention with the rest of U-Boot
where the parameter is ignored and callers are passing in 0.

If the cpu-idle-states is missing from the DT in the first place, do
not fail on removing in. Just move on and do not even print an error,
since not being able to remove something which is not there in the
first place is not an error and surely does not justify failing to
boot.
Turn the surrounding prints into debugs to reduce the useless noise.

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.

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.

These functions belong in cpu_func.h. Another option would be cache.h
but that code uses driver model and we have not moved these cache
functions to use driver model. Since they are CPU-related it seems
reasonable to put them here.
Move them over.

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.
