Yestoday I tested the earlyprintk stuff witout luck :-(
I simply added this CMDLINE earlycon=uart,mmio,0x11100000,115200n8
The drivers/serial/8250_early.o is build in the kernel but without

On the running kernel I see this.
Serial: 8250/16550 driver $Revision: 1.90 $ 5 ports, IRQ sharing enabled
serial8250.7: ttyS0 at MMIO 0x11100000 (irq = 0) is a 16550A
serial8250.7: ttyS1 at MMIO 0x11200000 (irq = 8) is a 16550A
serial8250.7: ttyS2 at MMIO 0x11400000 (irq = 9) is a 16550A
The console is console=ttyS0,115200n8 ....
