No change without dtb
I have also tried to add --mem-mim and --mem-max without any change.
I given mem according to what I saw in /proc/iomem
20000000-9fffffff : System RAM
20008000-207fffff : Kernel code
20900000-209a0c87 : Kernel data
So I gave --mem-min 0x30000000 --mem-max 0x9fffffff
Anyway, the result is always the same.
