Hi Michal,

Just tried your patch v2 against mainline master branch, it still 
doesn't work on my board.  I also checked your mainline-v20200312 
branch, it's exactly the same: no output from any UART other than "Debug 
uart enabled" on UART0 if I enable it in menuconfig as "early UART".

It's the same.  CONFIG_DEFAULT_DEVICE_TREE becomes "zynqmp-zcu100-revC" 
whatever I do, there is no trace of the value specified in the 
DEVICE_TREE environment variable.

 From the build using your mainline-v20200312 branch:

   default = "config_1";

where config_1 is

   description = "avnet-ultra96-rev1";

I haven't set up JTAG yet.

Cheers,
