| This driver supports NE2000 compatible cards (those based on DP8390, |
| DP83902 and similar). It can be used with PCMCIA/CF cards provided |
| that the CCR is correctly initialized. |
| |
| The code is based on sources from the Linux kernel (pcnet_cs.c, |
| 8390.h) and eCOS(if_dp83902a.c, if_dp83902a.h). Both of these 2 |
| wonderful world are GPL, so this is, of course, GPL. |
| |
| I developed and tested this driver on a custom PXA255 based system and |
| with a billionton CF network card connected to the PCMCIA interface of |
| the micro (have a look at README.PXA_CF for the support of this port). |
| |
| The options you have to specify in the config file are (with the |
| value for my board as an example): |
| |
| #define CONFIG_DRIVER_NE2000 |
| |
| - Enables the driver |
| |
| #define CONFIG_DRIVER_NE2000_BASE (0x20000000+0x300) |
| |
| - Address where the board is mapped |
| |
| #define CONFIG_DRIVER_NE2000_CCR (0x28000000+0x3f8) |
| |
| - Address of the CCR (card configuration register). It could be found |
| by enabling DEBUG in cmd_pcmcia.c. If this is not defined nothing is |
| done as far as PCMCIA support is concerned. |
| |
| #define CONFIG_DRIVER_NE2000_VAL (0x20) |
| |
| - The value to be written in the CCR. It selects among different I/O |
| spaces that could be used by the card. |
| |
| |
| Enjoy! |
