Add the addition of a bootconfig block at the end of an image as a
conversion type; while a bootconfig is mostly used in conjuntion with an
initramfs (i.e.: a cpio image or one of its compressed forms), having it
as a generic conversion type simplifies the implemntation and is ready
for future modifications at kernel side.
The following configurations variables are introduced (in a separate
bbclass, for further usage by other components):
- BOOTCONFIG_SOURCES: list of source files to be used as bootconfig,
to be found inside DEPLOY_DIR_IMAGE;
- BOOTCONFIG_TASKS: list of tasks deploying the bootconfig source
files specified in BOOTCONFIG_SOURCES to DEPLOY_DIR_IMAGE; an image
using the bootconfig modifier will depend on them.
