4ca42af8f5 ARM: imx: imx8m: Add 933 MHz PLL settings
Add settings for operating PLL at 933 MHz. This setting is useful in
case the LPDDR4 DRAM should operate at 1866 MHz or 3733 MT/s.

6ac4d44806 arm: imx: imx8mm: correct unrecognized fracpll frequency
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.

d9a7f1a913 arm: imx: imx8mm: clock: make debug output more descriptive
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.

e8bb990fe7 ARM: imx8m: fix imx_eqos_txclk_set_rate() type mismatch for LTO
When building imx8mp_evk_defconfig with LTO, the compiler complains
about type mismatch of function imx_eqos_txclk_set_rate() in file
  drivers/net/dwc_eth_qos.c:845:12
which contains a weak definition of this function, vs file
  arch/arm/mach-imx/imx8m/clock_imx8mm.c
which contains an implementation.

Change the type of this function in the implementation to fix this.

41b230bf29 iMX8M: Add support to enable CONFIG_IMX_HAB
Add some SOC level codes and build configurations to use HAB lib for
CONFIG_IMX_HAB (secure boot), like adding the SEC_CONFIG fuse, enable
fuse driver, CAAM clock function, and add CAAM secure RAM to MMU table.

The FSL_CAAM is temporally not enabled for iMX8M when CONFIG_IMX_HAB is set,
because we don't need the CAAM driver for SPL.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

Current DM CLK is a bit complicated, for simplity, let DM clk only
support enable/disable/get_rate. For the expected rate settings,
we use non-DM clk to do that. Then we could have simple DM clk for
i.MX and could also share between SPL/U-Boot proper.

clock_imx8mm.c is used for non CLK dm case, let's split

considering code size, malloc size requirement, the splittion
will make it easy to use non CLK dm in SPL stage.
