I tested this on LX2160 and get this error when booting into Linux:

    Loading Device Tree to 000000009fff6000, end 000000009fffff3e ... OK
gic_v3_its_get_gic_lpi_addr: failed to get gic-lpi-base syscon device

Starting kernel ...

[    0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd083]

I did not look closely yet. Any idea whats going wrong here?

Thanks,
Stefan
