Currently I get: Early serial console at I/O port 0x0 (options '') With this patch I get: Early serial console at MMIO 0x7ff80000 (options '') > We would report this as an IO port based mapping and not as MMIO.

For the case in which we just provide an address as an argument to the earlycon console type like: earlycon=msm_serial_dm,0xf991e000 We would report this as an IO port based mapping and not as MMIO. Simple fix to use the port->iotype to decide which message to print.
