You will have to implement it such that none of the existing board build/functionality breaks. Otherwise it will be impossible to get this merged. Is this series tested for High-Security (HS) J721E as well? cheers, -roger > > 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 > > Neha Malcom Francis (11): > j721e_evm: schema: yaml: Add general schema and J721E board config > files > ti: tools: config: Add board config class to generate config binaries > ti: etype: sysfw: Add entry type for sysfw > ti: etype: dm: Add entry type for TI DM > ti: etype: x509: Add etype for x509 certificate for K3 devices > ti: sysfw: Add support for packaging sysfw.itb > ti: tiboot3.bin: Remove tiboot3.bin target from makefile > ti: tispl.bin: Removed script that packages tispl.bin > ti: x509: Remove shell script used for signing > ti: dtsi: j721e: Use binman to package sysfw.itb and tiboot3.bin > ti: dtsi: j721e: Use binman to package tispl.bin > > Makefile | 2 + > arch/arm/dts/k3-j721e-a72-binman.dtsi | 86 + > .../k3-j721e-common-proc-board-u-boot.dtsi | 1 + > arch/arm/dts/k3-j721e-r5-binman.dtsi | 88 + > .../k3-j721e-r5-common-proc-board-u-boot.dtsi | 1 + > arch/arm/mach-k3/config.mk | 64 +- > board/ti/common/schema.yaml | 355 ++ > board/ti/j721e/Kconfig | 2 + > board/ti/j721e/config.yaml | 3162 +++++++++++++++++ > scripts/Makefile.spl | 4 - > test/py/requirements.txt | 1 + > tools/binman/entries.rst | 36 + > tools/binman/etype/ti_dm.py | 23 + > tools/binman/etype/ti_sysfw.py | 28 + > tools/binman/etype/x509_cert.py | 248 ++ > tools/binman/ftest.py | 21 + > tools/binman/test/225_ti_dm.dts | 13 + > tools/binman/test/232_ti_sysfw.dts | 13 + > tools/binman/test/232_x509_cert.dts | 18 + > tools/k3_fit_atf.sh | 123 - > tools/k3_gen_x509_cert.sh | 252 -- > tools/tibcfg_gen.py | 114 + > 22 files changed, 4227 insertions(+), 428 deletions(-) > create mode 100644 arch/arm/dts/k3-j721e-a72-binman.dtsi > create mode 100644 arch/arm/dts/k3-j721e-r5-binman.dtsi > create mode 100644 board/ti/common/schema.yaml > create mode 100644 board/ti/j721e/config.yaml > create mode 100644 tools/binman/etype/ti_dm.py > create mode 100644 tools/binman/etype/ti_sysfw.py > create mode 100644 tools/binman/etype/x509_cert.py > create mode 100644 tools/binman/test/225_ti_dm.dts > create mode 100644 tools/binman/test/232_ti_sysfw.dts > create mode 100644 tools/binman/test/232_x509_cert.dts > delete mode 100755 tools/k3_fit_atf.sh > delete mode 100755 tools/k3_gen_x509_cert.sh > create mode 100644 tools/tibcfg_gen.py >
