Something is a bit weird with my RPi3 in 64bit mode. uboot loads the the dtb file via ftp and then does a booti. For all non PREEMPT_RT kernels (PREEMPT, NONE, SMP=n, ...) everything works fine. For the PREEMPT_RT kernel uboot complains with U-Boot> booti 0x00080000 - 0x02600000 bootloader-commands: Wait for prompt Starting kernel (timeout 00:03:43) booti 0x00080000 - 0x02600000 ERROR: Did not find a cmdline Flattened Device Tree Starting kernel ... It's the same dtb in all cases. Not totally sure what is upsetting uboot here, maybe the load addresses don't work anymore? In short, I can't really say if v5.9-rt for ARMv8 works for me.
