The console=uartXXXXX parameter is just an alias for earlycon=uartXXXX.
This means it also accepts the uartclk parameter.

Start an early, polled-mode console on the 8250/16550
UART at the specified I/O port or MMIO address,
switching to the matching ttyS device later.
- MMIO inter-register address stride is either 8-bit
- (mmio), 16-bit (mmio16), or 32-bit (mmio32).
- If none of [io|mmio|mmio16|mmio32], <addr> is assumed
- to be equivalent to 'mmio'. 'options' are specified in
- the same format described for ttyS above; if unspecified,
- the h/w is not re-initialized.

both Xen and PowerPC hypervisors.
