After looking into the changeset ac58afdfac792c0583af30dbd9eae53e24c78b, 
  I find what I want to do has been done by you:-)

For those MIPS32 boards which only use IRQ_CPU, I think, we can provide 
a default plat_irq_dispatch() implemention, maybe like this:

asmlinkage plat_irq_dispatch(struct pt_regs *regs)
{
	unsigned int pending = read_c0_status() & read_c0_cause();
	int irq;

	irq = ffs(pending >> 8) - 1;
	return do_IRQ(irq, regs);
}

I this it will clean up more codes......

Best Regards,
