Frequency requested by ddrphy_init_set_dfi_clk from fracpll uses MHZ()
macro, which expands the value provided to the Hz range without taking into
account the precise Hz setting. This causes the frequency of 266 MHz not ot
be found in the imx8mm_fracpll_tbl, since it is entered there with a
precise Hz value. This in turn causes the boot hang in SPL, as proper DDR
fracpll frequency cannot be determined.
Correct the value in imx8mm_fracpll_tbl to match the one expanded by
MHZ(266) macro, rounding it down to MHz range only.

Clock initialization functionality has ambitious debug messages, which are
printed out when failures are triggered during execution:
- Separate frequency table lookup functions have the the same output that
makes it impossible to understand which function failed and produced the
output
- PLL decoding routine has a generic debug statement printed, which does
not state the actual value failed to be found
Extend the output for both cases with prefixing table lookup functions
output with function name, and report the failed value in PLL decoding
routine.

On ARM, the gd pointer is stored in registers r9 / x18. For this the
-ffixed-r9 / -ffixed-x18 flag is used when compiling, but using global
register variables causes errors when building with LTO, and these
errors are very difficult to overcome.
Richard Biener says [1]:
Note that global register vars shouldn't be used with LTO and if they
are restricted to just a few compilation units the recommended fix is
to build those CUs without -flto.
We cannot do this for U-Boot since all CUs use -ffixed-reg flag.
It seems that with LTO we could in fact store the gd pointer differently
and gain performance or size benefit by allowing the compiler to use
r9 / x18. But this would need more work.
So for now, when building with LTO, go the clang way, and instead of
declaring gd a global register variable, we make it a function call via
macro.

Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.
This transformation was done with the following coccinelle patch:

- reset_cpu(argvalue)

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.

- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet
- GPIOs
- I2C
Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper
ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.

The drivers/clk/imx/*.c are used for CLK dm case, the
clock_imx8mm.c is used for non CLK dm case, let's split
it. Sometimes it is hard to enable CLK dm in SPL stage,
considering code size, malloc size requirement, the splittion
will make it easy to use non CLK dm in SPL stage.

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.
