The i.MX6DP and i.MX6QP incorporate NoC interconnect logic
which needs to be configured in order to use external DDR memory.
This patch enables the SPL to configure the necessary registers

The FIT config node has reversed ATF and u-boot: ATF is set to 'firmware' but
u-boot is set to 'loadables'.
This script can work previously because spl fit driver wrongly appends fdt to
all loadable images. With the issue fixed in commit 9d15d1d1c2 ("Revert
"common: spl_fit: Default to IH_OS_U_BOOT if FIT_IMAGE_TINY enabled"") the
u-boot in 'loadables' does not have fdt appended and fails to work. So correct
the script by moving u-boot to 'firmware' and ATF to 'loadables'.

Currently imx-specific bootaux command doesn't support ELF format
firmware for Cortex-M4 core.
This patches introduces a PoC implementation of handling elf firmware
(load_elf_image_phdr() was copy-pasted from elf.c just for PoC).
ELF64 binaries isn't supported yet.
This has the advantage that the user does not need to know to which
address the binary has been linked to. However, in order to handle
and load the elf sections to the right address, we need to translate the
Cortex-M4 core memory addresses to primary/host CPU memory
addresses (Cortex A7/A9 cores).
This allows to boot firmwares from any location with just using
bootaux, e.g.:
> tftp ${loadaddr} hello_world.elf && bootaux ${loadaddr}
Similar translation table can be found in the Linux remoteproc
driver [1].

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.

Place imx_ddr_size() into a separate file.
The motivation for doing this is to be able to easily reuse
imx_ddr_size() on i.MX7ULP.
Currently imx_ddr_size() is inside arch/arm/mach-imx/cpu.c, which
is not built for i.MX7ULP.
Changing the logic to allow building cpu.c for i.MX7UP would
require adding several ifdef's, leading to a not a very elegant
solution.
To allow better reuse, just place imx_ddr_size() into a common
mmdc_size.c file.

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

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.
