| 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 |
| Probing IDE interface ide0... |
| hda: CF500, CFA DISK drive |
| |
| This fixes OpenWrt ticket #7061: https://dev.openwrt.org/ticket/7061 |
