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. | |
| 34 | ||
| 35 | ||
| 36 | Enjoy! | |
