kernel-fitimage: adding support for Initramfs bundle and u-boot script
This commit adds Initramfs bundle support to the FIT image in addition
to u-boot boot script capability.
These new features are selectable.
In case of Initramfs, the kernel is configured to be bundled with the rootfs
in the same binary (ie: zImage-initramfs-<machine>.bin). When the kernel is
copied to RAM and executed, it unpacks the Initramfs rootfs.
For more information about Initramfs please read:
https://www.kernel.org/doc/Documentation/filesystems/ramfs-rootfs-initramfs.txt
For more details about the Initramfs bundle and boot script implementation
please check the kernel-fitimage.bbclass paragraph in Yocto reference
or mega manual.
Current limitations:
- Initramfs bundle FIT support has been tested on ARM 32-bit
- The kernel image type in case of ARM 32-bit is zImage
