QEMU brings it's own device tree at\n a memory address. U-Boot expects public keys in it's own DT though.\n So merge both.\n - (optionally) enforce signatures so we can't accidentally boot\n unsigned fit images. Quite an easy oversight, esp when qemu\n previously didn't even use the built in DT.\n - make iminfo verify configuration signatures, not just image hashes\n\nChanges in v3:\n- enable CONFIG_OF_OMIT_DTB=n in defconfig\n- add error returns\n- document decission about dt merging direction\n- make log_err use stdout too\n- clarify error message when no keys were found\n- change printfs to log_err\n- reword Kconfig\n- keep FIT_SIGNATURE_REQUIRED off by default\n- use log_err instead of printf in fit_config_verify_required_keys()\n- don't make iminfo fail unless FIT_SIGNATURE_REQUIRED is set\n- update fit_all_configurations_verify documentation\n- stub fit_all_configurations_verify unless FIT_SIGNATURES\n\nChanges in v2:\n- introduce FIT_SIGNATURE_REQUIRED\n- document fit_all_configurations_verify()\n\nLudwig Nussel (4):\n qemu: overlay signature nodes\n mkimage: define log_err and log_info\n image-fit-sig: Optionally require signatures\n iminfo: also verify signatures\n\n board/emulation/qemu-arm/qemu-arm.c | 50 ++++++++++++++++++++++++--\n boot/Kconfig | 10 ++++++\n boot/image-fit-sig.c | 22 +++++++-----\n boot/image-fit.c | 54 +++++++++++++++++++++++++++++\n boot/image-pre-load.c | 3 --\n cmd/bootm.c | 7 ++++\n configs/qemu_arm64_defconfig | 1 +\n include/image.h | 8 +++++\n tools/mkimage.h | 5 +++\n 9 files changed, 146 insertions(+), 14 deletions(-)" }
