| 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! | |
