Hi Tim, thanks for the info!

What is the actual test made to check if mini-uart is selected? I can't get
firmware to trigger this behaviour with 64-bit upstream kernel/dts. Note that I
see the core clk setup at 200MHz just before having VC4 set it to 500MHz.
The only thing I've got on my config.txt is:
enable_uart=1
arm_64bit=1
Maybe we're missing some kind of DT alias upstream?
