Comment 5 for bug 1847596

For arm64 /boot/firmware/config.txt looks like this (this time before the change):

enable_uart=1
kernel=kernel8.bin
device_tree_address=0x03000000
dtparam=i2c_arm=on
dtparam=spi=on
arm_64bit=1

again, added the dtoverlay and rebooted. After that screen is looking normal.
