I am not sure if I have understood your use-case correctly but the steps you
are performing are like this?
1. Power up your board
2. u-boot loads a Linux kernel (and possibly ramdisk and device tree) into RAM
3. u-boot loads your L4Re image
4. L4Re is started with uvmm
Is my understanding correct?
Regards,
Matthias.
