Subject: [PATCH] pci: IDE fix
These are standard probing messages when using pdc202xx_old:
pdc202xx_old 0000:00:01.0: IDE controller (0x105a:0x0d30 rev 0x02)
PCI: Enabling device 0000:00:01.0 (0004 -> 0007)
PCI: Fixing up device 0000:00:01.0
0000:00:01.0: (U)DMA Burst Bit DISABLED Primary PCI Mode Secondary PCI Mode.
0000:00:01.0: FORCING BURST BIT 0x00->0x01 ACTIVE
pdc202xx_old 0000:00:01.0: 100% native mode on irq 6
With the default MAX_HWIFS value after above we get:
ide2: BM-DMA at 0x0400-0x0407
ide3: BM-DMA at 0x0408-0x040f
Probing IDE interface ide2...
hde: CF500, CFA DISK drive
As you can see it's ide2 + ide3 and hde.
With this patch applied we get:
ide0: BM-DMA at 0x0400-0x0407
ide1: BM-DMA at 0x0408-0x040f

hda: CF500, CFA DISK drive
