The kernel device IRQs and Frame mappings generated by this script will only come from nodes specified in the seL4,kernel-devices property of the chosen node. Previously these devices were inferred by the script but this led to false matching and didn't support easily overriding which devices to match under different configurations or across different platforms. Explicitly specifying which devices from the device tree will be used in the kernel makes it easier to check which devices the kernel is actually using and makes it easier to change on a per platform or per configuration basis.
