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.
