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.

hvc<n> Use the hypervisor console device <n>. This is for
both Xen and PowerPC hypervisors.
The console=uartXXXXX parameter is just an alias for earlycon=uartXXXX. This means it also accepts the uartclk parameter. Signed-off-by: Raul E Rangel <rrangel@chromium.org> --- Documentation/admin-guide/kernel-parameters.txt | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-)
