eade90fd00 arm64: zynqmp: Describe images without TF-A
U-Boot can run out of EL3, NS-EL2 and NS-EL1. Currently default
configuration is NS-EL2 with TF-A but when TF-A is not passed and
configured images can still boot just fine. That's why support this
configuration and describe it via binman.

f339584992 arm64: zynqmp: Use DTB address base from .config
CONFIG_XILINX_OF_BOARD_DTB_ADDR holds DTB address which U-Boot is checking.
Currently address in binman match default value but macro can be used
directly.
Also sync node name (s/hash-1/hash/) and sync location to have the same
order load/hash/image.

All binman DTSes are compiled that's why also guard
CONFIG_XILINX_OF_BOARD_DTB_ADDR which depends on OF_BOARD || OF_SEPARATE
which is a problem for mini configurations which are using OF_EMBED.

89e26b49a9 arm64: zynqmp: Fix TEE loading address and add hash
There is incorrect loading address listed for TEE.
CONFIG_BL32_LOAD_ADDR should be used.
Also there is missing hash for this entry which is present for other nodes.

0184f3eead arm64: zynqmp: enable u-boot itb generation via binman if SPL is enabled
Output images are generated via Binman only if SPL is enabled, as
there is no consumer for them otherwise. An #ifdef check ensures that
when SPL is enabled, Binman generates the U-Boot ITB. If SPL is disabled,
ITB generation is skipped since the ITB format is supported only by SPL.
Without SPL, generating such an image is unnecessary, as it would not be
used

The second reason is that when a DTB is passed, the current logic cannot
handle it without an additional step in U-Boot to parse an appended FIT
image and enable board-specific code to select the correct DTB config.
The MULTI_DTB_FIT configuration should be used if support for multiple
DTBs is required, but SPL is not being used.

2eb8cd5bd4 arm64: zynqmp: Add binman description for SOM
There is necessary to do some steps to compose boot images. These steps
were in scripts in layers for a while. That's why introduce description via
binman to simplify wiring and remove all scripting around.
This should make sure that everybody is up2date with the latest versions.

The first step is to create fit image with DTBs with descriptions in
configuration node which is written as regular expression to match all SOM
versions.
Description is there for k24 and k26 in spite of low level psu_init
configuration is different. The reason is that it goes to u-boot.itb image
which is the same for k24 and k26.
u-boot.itb is another image which is generated. It is normally generated
via arch/arm/mach-zynqmp/mkimage_fit_atf.sh but this script is supposed to
be deprecated.
FIT image by purpose is using 64bit addresses to have default option to
move images to high DDR (above 4GB). TF-A and TEE are optional components
but in the most cases TF-A is present all the time and TEE(OP-TEE) is used
by some configurations too.

3rd generated image is boot.bin with updated user field which contains
version number. This image can be used with updated Image Selector
which supports A/B update mechanisms with rollback protection.

4th image is image.bin which binary file which contains boot.bin and
u-boot.itb together and can be programmed via origin Image Selector.
This image can be also used for creating one capsule which contains both
boot images (in SPL boot flow).
