You mean "adding" ?  I think now we can select
GENERIC_HARDIRQS_NO__DO_IRQ for all MACH_VR41XX boards.

Also I think most codes in vr41xx/nec-cmbvr4133/irq.c can be removed
if we made I8259A_IRQ_BASE customizable, but that would be another
story...

This number is fixed to zero because that's what all the old ISA drivers
expect, the ISA boards have printed on etc...

It's not really related as 8259 is programmed to generate vectors 0x20 to 0x2F for x86 but the the IRQs start from zero anyway...
