Hello I have successfully started a kernel (5.5.0-rc7-next-20200124-00075-gd1ea5e663326) with this serie. Thanks for your help by IRC, updating firmware seems to did the trick. The kernel panic just after with "OF: reserved mem: failed to allocate memory for node 'linux,cma'" but that's another story. Tested-by: Corentin Labbe <cla...@baylibre.com> Thanks
