+OF_EARLYCON_DECLARE(mps2, "arm,mps2-uart", mps2_early_console_setup);IIRC Peter Hurley mentioned you don't need to put both anymore, OF_ one is enough.I've just tried with OF_ only and seems it works fine. Thanks for pointing at it!..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.
Peter, what is your comment on this? -- With Best Regards, Andy Shevchenko
