Add support for building alternative kernel images into a FIT image instead of
using linux.bin. An incomplete solution with a similar goal was added in in
commit 9c8ef2119949 ("kernel-fit-image: control kernel section with
FIT_LINUX_BIN") and subsequently reverted in commit 6eae261b6f52 ("Revert
"kernel-fit-image: control kernel section with FIT_LINUX_BIN"") due to missing
features, lack of tests and the submitter having abandoned their approach.
With the new approach, compression is now either handled as part of the
FIT image (KERNEL_FILENAME) or the image is considered to be compressed already
(KERNEL_FILENAME_COMPRESSED). The option to let the kernel recipe do the
compression and store the result in the image deploydir as linux.bin is
preserved for backwards compatibility, but will result in a deprecation warning.
Our main use case for this is to support building a FIT image with an EFI
application as kernel (with FIT_OS = "efi").
v2: do not hardcode kernel filename to bzImage in
fitimage.KernelFitImageRecipeTests.test_fit_image_kernel_filename selftest
to fix build on non-x86 machines in PATCH 2/3
Nora Schiffer (3):
kernel-uboot: move FIT_KERNEL_COMP_ALG to image-fitimage.conf
kernel-fit-image: reintroduce option to replace kernel image
kernel-fit-extra-artifacts: skip building linux.bin if unneeded
