[REGRESSION] No serial console output on BeagleBone Black

[Bartosz Golaszewski]

Hi Tero,

I tried booting a BeagleBone Black Rev C with current git, but got no
output after u-boot's "Starting kernel ...". Bisect points at commit
e3bc5358 ARM: dts: am33xx: add minimal l4 bus layout with control
module support. Let me know if you need any more info.

Best regards,
Bartosz Golaszewski
