@Ben,
   As you suggested, I moved P8 timer code to separate file. But now I'm 
thinking it may be good to have single file (sbe.c) and add all SBE related code 
their (both P8 timer code and new P9 code).

In P8, we have used direct SCOMs for SBE timer. But from P9 onwards we are 
getting MBOX messages for SBE operations. So we can have something like below


void sbe_timer_init(void)
{
	if (proc_gen == proc_gen_p8)
		p8_sbe_timer();
	else
		sbe_timer();
}

Let me know which one is better.
