Can you please try to boot with appended DTB? Some versions of the
Marvell bootloader tend to do horrible modifications to the FDT, making
assumptions that might be true with their Linux LSP, but not with the
mainline kernel. Using appended DTB is a way of making sure that their
bootloader will not touch the kernel DTB.

Thanks,

Thomas
