Hi,

At present rockchip 64-bit boards make use of a FIT-generator script written in Python. The script supports splitting an ELF file into several 'loadable' nodes in the FIT. Binman does not current support this feature.
This series adds binman support for ELF splitting. This works by adding a new 'fit,operation' property to the FIT subnodes, allowing this new way of generating nodes.
It also provides support for optional entries, by allowing them to be marked absent when the contents are obtained.
Some other fixes and improvements are needed along the way.
A new, common binman description is added for 64-bit boards which includes the required u-boot.itb file.
The existing script is removed, so that only a few zynq boards are now using a SPL_FIT_GENERATOR script:
avnet_ultrazedev_cc_v1_0_ultrazedev_som_v1_0 xilinx_zynqmp_virt
Migration of those is hopefully in progress.
Note however that tools/k3_fit_atf.sh remains, used by a few boards that enable CONFIG_TI_SECURE_DEVICE so this series is copied there too:

In any case they should really be using binman for the image generation.
Changes in v6:
- Add new patch to update entry docs
- Add new patch to disable USE_SPL_FIT_GENERATOR by default
- Add new patch to allow a binman entry to be marked absent
- Update op-tee to support new v1 binary header
Please ignore this version as it does not have full test coverage. I will send v7.
