44 * post_reset is the time the kernel should stall to prevent anyone from
45 * accessing the PCI bus once #RESET is de-asserted.
46 * PCI spec somewhere says 1 second but with multi-PCI bus systems,
47 * this makes the boot time much longer than necessary.
48 * 20ms seems to work for all the HP PCI implementations to date.
