[ale] hdd detection

[cfowler at outpostsentinel.com (Christopher Fowler)]

I have a device that has only one IDE port.  Not 2.  Linux keeps trying
to detect the drives at hdc and hdd.  This slows down boot.

ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
hda: PQI IDE DiskOnModule, ATA DISK drive
hdc: IRQ probe failed (0xfef8)
hdc: IRQ probe failed (0xfef8)
hdc: no response (status = 0x0a), resetting drive
hdc: IRQ probe failed (0xfef8)
hdc: no response (status = 0x0a)
hdd: IRQ probe failed (0xfef8)
hdd: IRQ probe failed (0xfef8)
hdd: no response (status = 0x0a), resetting drive
hdd: IRQ probe failed (0xfef8)
hdd: no response (status = 0x0a)
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: attached ide-disk driver.
hda: 64000 sectors (33 MB) w/1KiB Cache, CHS=31/32/63


Is there a way to tell the kernel that hdc and hdd or ide1 does not
exist?
