| wdenk | f806271 | 2005-01-09 23:16:25 +0000 | [diff] [blame] | 1 | This driver supports NE2000 compatible cards (those based on DP8390, |
| 2 | DP83902 and similar). It can be used with PCMCIA/CF cards provided |
| 3 | that the CCR is correctly initialized. |
| 4 | |
| 5 | The code is based on sources from the Linux kernel (pcnet_cs.c, |
| 6 | 8390.h) and eCOS(if_dp83902a.c, if_dp83902a.h). Both of these 2 |
| 7 | wonderful world are GPL, so this is, of course, GPL. |
| 8 | |
| 9 | I developed and tested this driver on a custom PXA255 based system and |
| 10 | with a billionton CF network card connected to the PCMCIA interface of |
| 11 | the micro (have a look at README.PXA_CF for the support of this port). |
| 12 | |
| 13 | The options you have to specify in the config file are (with the |
| 14 | value for my board as an example): |
| 15 | |
| 16 | #define CONFIG_DRIVER_NE2000 |
| 17 | |
| 18 | - Enables the driver |
| 19 | |
| 20 | #define CONFIG_DRIVER_NE2000_BASE (0x20000000+0x300) |
| 21 | |
| 22 | - Address where the board is mapped |
| 23 | |
| 24 | #define CONFIG_DRIVER_NE2000_CCR (0x28000000+0x3f8) |
| 25 | |
| 26 | - Address of the CCR (card configuration register). It could be found |
| 27 | by enabling DEBUG in cmd_pcmcia.c. If this is not defined nothing is |
| 28 | done as far as PCMCIA support is concerned. |
| 29 | |
| 30 | #define CONFIG_DRIVER_NE2000_VAL (0x20) |
| 31 | |
| 32 | - The value to be written in the CCR. It selects among different I/O |
| 33 | spaces that could be used by the card. |

| 36 | Enjoy! |
