  • 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!
