..and the reason for that was that I had stdout pointing at uart node.
Now, while testing v4 I end-up with configuration:

1) no EARLYCON_DECLARE in mps2-uart.c
2) stdout not set
3) cmdline has "earlycon=mps2,0x40004000 console=/dev/ttyMPS"

and I don't see bootconsole, but if I avoid 1) everything works fine.
So, I'd leave EARLYCON_DECLARE in this patch.
