688 * This is a two part issue. The first part is that some of
689 * our older controllers have an issue in which the slot's PCI
690 * INT# is NOT qualified by the IRQ routing bit (PCI reg. 3Eh
691 * bit 7). Regardless of the IRQ routing bit, if NO ISA IRQ
692 * is selected (ExCA register 03h bits 3:0, of the slot, are
693 * cleared) we will generate INT# if IREQ# is asserted. The
694 * second part is because some PC Cards prematurally assert
695 * IREQ# before the ExCA registers are fully programmed. This
696 * in turn asserts INT# because ExCA register 03h bits 3:0
697 * (ISA IRQ Select) are not yet programmed.
699 * The fix for this issue, which will work for any controller
700 * (old or new), is to set ExCA register 03h bits 3:0 = 0001b
701 * (select IRQ1), of the slot, before turning on slot power.
702 * Selecting IRQ1 will result in INT# NOT being asserted
703 * (because IRQ1 is selected), and IRQ1 won't be asserted
704 * because our controllers don't generate IRQ1.
