void

early_sn_setup - early setup routine for SN platforms

Sets up an initial console to aid debugging. Intended primarily for bringup. See start_kernel() in init/main.c.

sn_serial_console_early_setup - Sets up early console output support

Register a console early on... This is for output before even sn_sal_serial_cosnole_init is called. This function is called from setup.c. This allows us to do really early polled writes. When sn_sal_serial_console_init is called, this console is unregistered and a new one registered.
