e663c703b1 imx8m: soc: probe clock device in arch_cpu_init_dm
Because we need to get cpu freq in print_cpuinfo at very early stage,
so we need to make sure the ccm be probed.

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.

5b20d141f2 imx: Kconfig: Reduce default CONFIG_CSF_SIZE
The default CSF_SIZE defined in Kconfig is too high and SPL cannot
fit into the OCRAM in certain cases.

The CSF cannot achieve 0x2000 length when using RSA 4K key which is
the largest key size supported by HABv4.

According to AN12056 "Encrypted Boot on HABv4 and CAAM Enabled Devices"
it's recommended to pad CSF binary to 0x2000 and append DEK blob to
deploy encrypted boot images.

As the maximum DEK blob size is 0x58 we can reduce CSF_SIZE to 0x2060
which should cover both CSF and DEK blob length.

Update default_image.c and image.c to align with this change and avoid
a U-Boot proper authentication failure in HAB closed devices:

Authenticate image from DDR location 0x877fffc0...
bad magic magic=0x32 length=0x6131 version=0x38
bad length magic=0x32 length=0x6131 version=0x38
bad version magic=0x32 length=0x6131 version=0x38
spl: ERROR:  image authentication fail

772b55723b imx: Introduce CONFIG_SPL_FORCE_MMC_BOOT to force MMC boot on falcon mode
This change tries to fix the following problem:

- The board boots (to be more precise - ROM loads SPL) from a slow SPI-NOR
  memory.
  As a result the spl_boot_device() will return SPI-NOR as a boot device
  (which is correct).

- The problem is that in 'falcon boot' the eMMC is used as a boot medium to
  load kernel from its partition.
  Calling spl_boot_device() will break things as it returns SPI-NOR device.

To fix this issue the new CONFIG_SPL_FORCE_MMC_BOOT Kconfig flag is
introduced to handle this special use case. By default it is not defined,
so there is no change in the legacy code flow.

CONFIG_MX6_OCRAM_256KB which allows using the full size on boards which
don't need to support the SL/DL variants. This allows for an SPL size of
