Devices that belong to the K3 architecture require SYSFW which is a FIT image consisting of a signed system firmware image and board config binaries.
Board config binaries are needed to bring up SYSFW during U-Boot SPL startup. The board config data is given in YAML as input. These board configs contain board-specific information such as resource management, power management and security.
The following series intends to plumb the system firmware generation into U-Boot using binman for packaging. Thus it will eliminate the need for additional custom repositories for SYSFW generation and also moves t owards the community standard build flow. We use binman to package tiboot3.bin and sysfw.itb images.
These images also require x509 certificates which are created using the etype x509-cert.
The series also plumbs the generation of tispl.bin into the build flow. This image is required for loading u-boot in K3 devices. The image is packaged using ATF, OPTEE and DM (Device Manager).
Please note that the following series has implemented the above for J721E general purpose board. The board configs and device trees added are specific to J721E GP devices.
Also note the introduction of three new etypes: ti-sysfw, ti-dm and x509-cert.
On running CI tests on Github, errors were produced during world builds of keystone2_keystone3 and siemens (I0T2050 which is based on AM65x). This patch series is intended for only J721E and future work is to expand to the remaining K3 devices as well. The errors that come are mainly due to the boards other than J721E trying to generate tispl.bin.
v2: - Added etype x509-cert for creating x509 Texas Instruments certificate binary - Added packaging of tiboot3.bin - Packaging of tiboot3.bin and sysfw.itb using new etype x509 - sysfw --> ti-sysfw - Reformatted and re-arranged patches - Removed k3_fit_atf.sh and k3_gen_x509_cert.sh as their functionality is provided by binman now
