Hi Pavel, I can confirm that your branch and the RTEMS git head work on my Pi A+ and Pi Zero now.
The console works when connected. For me, it will not automatically switch to the serial port if the HDMI cable is not connected. I have to comment out the cmdline.txt console switches. The Pi 2 works too, but with the older firmware. I still need to debug that. At least I can get back to trying the recently submitted SPI code.
