kASLR support in kernel requires a random number to be passed via chosen/kaslr-seed propert. sec_firmware generates this random seed which can then be passed in the device tree node
Is that functionality generic that it can be consumed by other devices?
Sec firmware is proprietary firmware which provides this random seed using HW engine on NXP devices. Other devices would need to generate their own random seed to be passed as this property.
