Our new U-BOOT for the imx8mp_iot_gate complains about the size
of the device tree being zero bytes. This is because it no longer
provides the kernel boot arguments via ATAGS, but passes them via
by injecting them in the flattened device tree..
This commit adds a minimal dtb file to the FIT image to satisfy U-BOOT.
Issue #5354
This disambiguates the boot images installed for base-hw from those
installed for base-nova.
Note that the image.elf file for other kernels (i.e., NOVA) is not
named image-<kernel>.elf at this point because this would prevent the
update from a pre-24.04 Sculpt system to a later one as the grub.cfg
is not touched by the old update mechanism. So after a system update,
grub would keep loading the last installed image.elf.
Issue #5182
The argument is superfluous because only run/image/uboot evaluated it
anyway, and the argument is always boot/image.elf. With this change, the
official semantics of run_image become: "replace the boot/image.elf file
by platform-specific file(s) at boot/ that can actually be booted".
Issue #4730
Both modules were quite similar except the the name of the FIT image
(image.itb) and the mkimage command line. FIT images are now produced by
the following RUN_OPT.
RUN_OPT += --include image/uboot --image-uboot-fit
Issue #4693
By making the use of gzip's '--best' option configurable and disabling it
by default, this patch noticably reduces the built-test cycle from 15 to
10 seconds when integrating the Sculpt system image for the PinePhone.
Fixes#4693
