695 * This is a two part issue. The first part is that some of
696 * our older controllers have an issue in which the slot's PCI
697 * INT# is NOT qualified by the IRQ routing bit (PCI reg. 3Eh
698 * bit 7). Regardless of the IRQ routing bit, if NO ISA IRQ
699 * is selected (ExCA register 03h bits 3:0, of the slot, are
700 * cleared) we will generate INT# if IREQ# is asserted. The
701 * second part is because some PC Cards prematurally assert
702 * IREQ# before the ExCA registers are fully programmed. This
703 * in turn asserts INT# because ExCA register 03h bits 3:0
704 * (ISA IRQ Select) are not yet programmed.
706 * The fix for this issue, which will work for any controller
707 * (old or new), is to set ExCA register 03h bits 3:0 = 0001b
708 * (select IRQ1), of the slot, before turning on slot power.
709 * Selecting IRQ1 will result in INT# NOT being asserted
710 * (because IRQ1 is selected), and IRQ1 won't be asserted
711 * because our controllers don't generate IRQ1.
713 * Other, non O2Micro controllers will generate irq 1 in some
714 * situations, so we can't do this hack for everybody. Reports of
715 * keyboard controller's interrupts being suppressed occurred when
