|
* 1. Probe driver for the Malta's UART ports:
|
|
*
|
|
* o 2 ports in the SMC SuperIO
|
|
* o 1 port in the CBUS UART, a discrete 16550 which normally is only used
|
|
* for bringups.
|
|
*
|
|
* We don't use 8250_platform.c on Malta as it would result in the CBUS
|
|
* UART becoming ttyS0.
|
|
*
|
|
* 2. Register RTC-CMOS platform device on Malta.
