* Use Genimage for declarative image layout instead of s[fg]disk and dd
* Change partition type to hybrid for M1, M1S and Green
This is what it really is, so just make sure only one "fix" function is
called.
* Change efi BOOT_SYS to gpt
There is no reason to have separate efi and boot sys, since all boards
that use efi also use grub as the loader.
* Change BOOT_SYS to more explanatory PARTITION_TABLE_TYPE
* Add units to DISK_SIZE
* Add forced-primary patch and use it in MBR images
* Avoid disabling SC2155, remove old comments
* Support custom sized SPL/raw boot region
This is required for Rockchip which by default stores the U-Boot FIT
image at the 8MiB offset.
* Ignore shellcheck warning
