The FIT image support in OE is quite limited:
1) No support to build an arbitrary number of FIT images since the FIT
image generation is tightly coupled to the kernel image.
2) A lot of U_BOOT-specific variables which may not be necessary for
other bootloaders.
3) No usage of the meta-oe signing.bbclass for signed FIT images.
This alternative class is added to solve the above-mentioned problems:
1) The class can be inherited by an arbitrary number of
<fit-image-name>.bb recipes to generate FIT images
2) No U_BOOT-specific variables are used
3) <fit-image-name>.bb recipes can prepend the do_fitimage() to
provide the key using the signing.bbclass e.g.:
do_fitimage:prepend() {
signing_prepare
signing_use_role "${FITIMAGE_SIGNING_KEY_ROLE}"
}
Then enable and configure signing as follows:
FITIMAGE_SIGN = "1"
FITIMAGE_MKIMAGE_EXTRA_ARGS = "--engine pkcs11"
FITIMAGE_SIGN_KEYDIR = "${PKCS11_URI}
This class is inspired by the meta-phytec fitimage.bbclass [1].
