It is not specific to any one bootloader, as it is supported by U-Boot, coreboot, Linuxboot, Tianocore and Barebox. This series adds support for building a FIT as part of the kernel build. This makes it easy to try out the kernel - just load the FIT onto your tftp server and it will run automatically on any supported arm64 board. The script is written in Python, since it is easy to build a FIT using the Python libfdt bindings. For now, no attempt is made to compress files in parallel, so building the 900-odd files takes a while, about 6 seconds with my testing. The series also includes a few minor clean-up patches. [1] https://github.com/open-source-firmware/flat-image-tree Changes in v7: - Drop the kbuild tag - Add Image as a dependency of image.fit - Drop kbuild tag - Add dependency on dtbs - Drop unnecessary path separator for dtbs - Rebase to -next Changes in v6: - Drop the unwanted .gz suffix Changes in v5: - Drop patch previously applied - Correct compression rule which was broken in v4 Changes in v4: - Use single quotes for UIMAGE_NAME Changes in v3: - Drop temporary file image.itk - Drop patch 'Use double quotes for image name' - Drop double quotes in use of UIMAGE_NAME - Drop unnecessary CONFIG_EFI_ZBOOT condition for help - Avoid hard-coding "arm64" for the DT architecture Changes in v2: - Drop patch previously applied - Add .gitignore file - Move fit rule to Makefile.lib using an intermediate file - Drop dependency on CONFIG_EFI_ZBOOT - Pick up .dtb files separately from the kernel - Correct pylint too-many-args warning for write_kernel() - Include the kernel image in the file count - Add a pointer to the FIT spec and mention of its wide industry usage - Mention the kernel version in the FIT description Simon Glass (2): arm64: Add BOOT_TARGETS variable arm64: boot: Support Flat Image Tree MAINTAINERS | 7 + arch/arm64/Makefile | 13 +- arch/arm64/boot/.gitignore | 1 + arch/arm64/boot/Makefile | 6 +- scripts/Makefile.lib | 13 ++ scripts/make_fit.py | 289 +++++++++++++++++++++++++++++++++++++ 6 files changed, 326 insertions(+), 3 deletions(-) create mode 100755 scripts/make_fit.py
