|  | 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! |
