Thanks a lot Geert and Benjamin for your response.
Code is indeed calling register_console from three different places
1) con_init()[name-tty],
2) serial8250_console_init()[name-ttyS],

Among these, 8250 must be the active one. Also

If you place any value on your time or development

This adds uic_mask_ack_irq() callback to PowerPC 4xx uic code
to avoid kernel crash. It is used for edge-triggered interrupts
