FIT public key is usually passed in via board DT. Usual way to use barebox with QEMU Virt however is to use DT supplied by Qemu and apply overlay to it. mkimage doesn't generate overlay DTB though. To make barbebox Qemu Virt behave like other boards, let's define a dummy DT that includes CONFIG_BOOTM_FITIMAGE_PUBKEY, which is merged with the barebox live device tree. v3 -> v4: - early exit initcall if compatible doesn't match - evaluate DTC_CPP_FLAGS for device tree overlays - rename overlay to reference board name - Rename older QEMU's /soc/flash@X to /flash@X v2 -> v3: - drop "support of_ensure_probed for top-level machine device" - switch from board driver back to initcall v1 -> v2: - support of_ensure_probed for top-level machine device - ensure qemu board driver is probed at postcore Ahmad Fatoum (6): boards: qemu-virt: apply overlay at postcore_initcall level kbuild: support DTC_CPP_FLAGS_file.dtbo boards: qemu-virt: compile overlay as such boards: qemu-virt: support passing in FIT public key of: implement of_move_node helper boards: qemu-virt: support older QEMU with /soc/flash common/boards/qemu-virt/Makefile | 6 +- common/boards/qemu-virt/board.c | 62 ++++++++++++------- common/boards/qemu-virt/fitimage-pubkey.dts | 7 +++ ...rlay-of-flash.dts => qemu-virt-flash.dtso} | 0 drivers/of/base.c | 18 ++++++ include/of.h | 1 + scripts/Makefile.lib | 1 + 7 files changed, 69 insertions(+), 26 deletions(-) create mode 100644 common/boards/qemu-virt/fitimage-pubkey.dts rename common/boards/qemu-virt/{overlay-of-flash.dts => qemu-virt-flash.dtso} (100%) -- 2.39.2
